FREquently asked questions

Where can I find institutional data?

Purdue University’s institutional data can be accessed via the following tools:

• Data Cookbook
  Metadata & Definitions
• Data Digest 
  A collection of public-facing dashboards meant to provide comprehensive quantitative information on the major dimensions of the university, including students, faculty, staff, and budget through interactive and visual information.
• Management Dashboards 
  A collection of internal dashboards meant to provide comprehensive quantitative information to support operations or strategic decision support through interactive and visual information. The Data Digest does contain some filters that are restricted, see How do I access the restricted filters on the Data Digest for more information.
• Cognos
  An IBM product that is Purdue’s enterprise reporting tool supported by the Business Intelligence Competency Center (BICC). Data has been grouped by subject matter, summarized into standard reports, and is available for custom reporting. Faculty and staff with a business need for data at a granular level should visit the BICC’s website.

What reports and dashboards should I use?

The Data Digest contains publicly available data and should be the first destination for various data items. 
For users not affiliated with the university, data can be requested via the Office of Legal Counsel.
If more information is needed beyond the Data Digest, users affiliated with the university can login to Management Dashboards. The Management Dashboards should be used to garner operational insights and guide strategic decision making.
If more granular information is needed beyond the Management Dashboards, users with a business need who are affiliated with the university can request access to the enterprise reporting tool, Cognos. More information about Cognos can be found on the BICC’s Website.

What is the difference between warehoused versus frozen data?

Warehoused data continues to be updated in real-time, typically daily. Frozen data is a snapshot of the data on the day it was copied and saved. Frozen data never changes.
Examples of frozen data include census data that captures enrollment, retention rates, and degrees conferred. Some frozen files are captured several weeks into the semester and some after the end of the semester. Frozen files are used for longitudinal reporting where point-in-time or trend analysis is needed. Mandated reporting, such as IPEDS, uses frozen data. See Data Cookbook for more information about the frozen data capture events.
Transactional data is often also available in the source systems, eg. Banner, Success Factors.
An example of live data is the number of students enrolled in a course on any given day. This number may change from day to day. It is used for daily operations where having the most current data is needed.  
To determine whether to use live versus frozen data, ask the questions:  

• Do I need to see how things stand now? Live data
• Do I need to see how things were when the event happened?  Frozen data
  

Does Purdue have a Factbook?

Yes, this information is available in the Data Digest.

How do I access the restricted filters on the Data Digest?

The restricted filters can be accessed by those affiliated with Purdue by having a current FERPA certification. It may take up to 24 hours between completion of the certification before access is granted.

How do I get access to Cognos?

Details about obtaining a Cognos license are available on the Business Intelligence Competency Center (BICC) website.

Where can I find training resources for Cognos?

The Business Intelligence Competency Center (BICC) provides Cognos Training on their website.

What is a census date and why is it important?

The census date is when official data are captured and ‘frozen’. For more information see the difference between live versus frozen data. The census event is typically completed early in each term.

Which other offices on campus also collect and provide data on students, faculty, and staff?

There are several offices on campus that collect data on Purdue University students, faculty, and staff and all have separate and vital reporting responsibilities. Human Resources Data and Analytics collects and provides data on faculty, staff, and graduate research/fellowships. Academic Data Managers provide college and departmental level information.

When are enrollment data updated for the current academic year?

Enrollment data are updated early in the fall semester, shortly after the fall census. The Business Intelligence Competency Center (BICC) maintains a list of key dates on their website.

Why is my number different than yours?

Numbers can vary for several reasons:

• Different assumptions 
  For example, you included lecturers in faculty count, but I excluded them.
• Different data sources 
  For example, you’re looking at live data and I’m looking at frozen (See live vs. frozen data for more information).
• Different systems: 
  For example, you’re looking at faculty counts from Elements whereas I’m looking at faculty counts from Success Factors.

What are the steps for adding students to a cohort?

To add students to a cohort, contact the Office of the Registrar and include a business need outlining the purpose, the proposed cohort code, the students to be included, and a maintenance plan for keeping the cohort up to date.

What is the Common Data Set (CDS)?

“The Common Data Set (CDS) initiative is a collaborative effort among data providers in the higher education community and publishers as represented by the College Board, Peterson’s, and U.S. News & World Report. The combined goal of this collaboration is to improve the quality and accuracy of information provided to all involved in a student’s transition into higher education, as well as to reduce the reporting burden on data providers.” – Common Data Set.

What is assessment?

In essence, assessment is a process comprised of purposeful and intentional planning aimed at collecting, analyzing and making meaningful connections of the data to inform decisions on effectiveness and drive continuous improvement. It is synonymous with continuous improvement, which you can learn more about in the Assessment 101 training video .
Typically, ‘assessment’ implies an emphasis on student learning, however, at Purdue, assessment describes gathering and analyzing data for “institutional, departmental, divisional, or agency effectiveness” (Upcraft & Schuh, 1996). At its core, assessment guides good practice (Erwin, 1991).

Why do we assess?

Assessment is a process of improvement; Assessment is primarily a mechanism that informs practitioners and serves to advance the practices encompassed in learning and development (across individuals or groups [students, faculty, staff, etc.], programs, institution or campus, and organization). By assessing, we are identifying areas of improvement and solutions that will lead to better outcomes. It is also a form of accountability in demonstrating that and the practice(s) of teaching and its outcomes- namely, learning and development- are reflective of best practices and equitable achievements (effectively contribute to equitable achievements?).
“In this sense, assessment for improvement is essentially an internal matter. In contrast, assessment data collected for the purpose of accountability are used primarily to demonstrate that the institution is using its resources appropriately to help students develop the knowledge, skills, competencies, and dispositions required to function effectively in the 21st century. The information is typically intended for external audiences” (Ewell, 2009).

What assessment services does IDA+A offer?

IDA+A offers the following: 

• Assistance to academic and co-curricular programs with evaluation of their curriculum, specialized and regional accreditation activities, and assessment of student learning achievements.
• Support the measurement of cognitive (e.g., critical-thinking, civic literacy, problem-solving, quantitative reasoning) and dispositional or affective outcomes. We can also support you in measuring skill-based outcomes measurement.
• Partnership with the University Curriculum Council (UCC) to coordinate and facilitate assessment activities for Embedded and Foundational Learning Outcomes (ELOs and FLOs, respectively) that make up the Core Curriculum.
• Survey methodology guidance and assistance with securing a sample of Purdue constituents to survey.
• Assist or manage the collection, analysis, and reporting of qualitative data (written responses to open-ended questions, interviews, focus groups, text, etc.) to inform your decision-making needs.
• Creation, validation, and longitudinal measures on important Campus Constructs (I.e., research constructs). 

What data collection support does IDA+A’s assessment team offer?

• IDA+A supports the collection of data via methods that occur outside of typical business intelligence mechanisms or information technology.
• IDA+A offers their expertise in both quantitative and qualitative methodologies, with a staff that provides a variety of diverse ontological, axiological, and epistemological views.
• IDA+A maintains a calendar (Career Account login required) of all known, large-scale survey efforts going on across student, faculty, staff, and other constituents.
• IDA+A assists our colleagues in combating survey or measurement fatigue by providing custom samples of students, faculty or staff. IDA+A draws these samples to ensure that researchers get a sufficient list of their target population while also ensuring that no individual on campus is contacted for surveys too frequently. Please use our project requests form to garner our services in this area.
• IDA+A provides expertise on survey methodology and measurement in education topics, such as, but not limited to: inference and error in surveys; target populations, sampling frames, and coverage errors; sample designs and sample errors; methods of data collection; messaging strategies;  nonresponse in sample surveys; questions and answers in surveys or questionnaires; post collection processing of survey data; assessment of qualitative results; principles and practices related to ethical survey and measurement in higher education.
• IDA+A maintains a library of important Campus Constructs. These are priority matters that have an approved best method of asking and measuring. Inside Qualtrics, any Purdue users can click on the Campus Constructs Library and then drag and drop any of the Campus Constructs question sets into their own survey instrument.
• IDA+A supports survey design and administration in Qualtrics. We can help ensure a survey will obtain unambiguous results and we can add desired bells and whistles to keep the survey interesting and unconfusing to respondents.
• IDA+A maintains a marketplace of survey metadata and contact information. Researchers wanting data about any topic can look there and see what exists and who to contact to learn what the previous survey found. 
• Additionally, IDA+A supports the collection, secure storage, and analysis of, plus reporting from qualitative data. IDA+A knows the value of this rich source of data and is happy to support you in garnering insights from it.
• IDA+A does not make judgements or recommendations about the propriety of any specific survey protocol. That is the job of the Institutional Review Board and IDA+A defers to the IRB.

Why can’t we rely on grades?

In short, measuring student achievement with grades is like measuring distances with unstandardized pieces of string. Course grades are designed or decided separately by hundreds of different instructors to match expectations for hundreds of different courses and hundreds of different learners, at any given point in time.
Academic departments often work to ensure that all sections of a course have similar content and similar requirements and expectations, but there is no similar effort to ensure that requirements for all courses across Purdue University require similar knowledge gain, or effort, or subject mastery to earn an ‘A’.

Why can’t we use student survey data in assessment?

Surveys are a method to indirectly assess student learning; via surveys or questionnaires students are able to self-assess their own learning achievement or developmental progress. However, students cannot be relied on to objectively evaluate the degree to which they have gained or demonstrated the necessary knowledge, attributes, and/or skills to earn a certain credential (e.g., degree, certificate) or succeed in a profession. Instead, objective standards or direct measures (rubrics, tests, quizzes, etc.) are needed to be established and maintained, and measured in non-subjective ways by experts with valid measures and methods to ascertain achievement of outcomes or competencies.

How is assessment data used?

Assessment is used for the continuous improvement of the organization engaging in the assessment activity or activities. Those who work with IDA+A can make decisions, modify practices, or take other actions based on our analysis of their data. For those at the beginning of their assessment journey, assessment data may be used simply to gather a baseline from which to inform future assessment.
At the outset of any project, IDA+A works with campus partners to understand and agree on how and with whom assessment data collected during the project is shared.

What is the difference between assessment and evaluation?

See above for the definition of assessment. Evaluation differs from assessment principally in its focus on the program or process rather than on the outcomes (whether they be learning, developmental, affective, kinesthetic or behavioral). As defined by Russ-Elft and Preskill (2009), “Evaluation is a form of inquiry that seeks to address critical questions concerning how well a program, process, product, system, or organization is working.”
In other words, the question is not so much “To what degree did the outcome occur?”, but is instead “Is the program or process functioning to its highest and best capacity?”

What is the difference between assessment and research?

See above for the definition of assessment. Research is defined as “…a truth-seeking activity which contributes to knowledge, aimed at describing or explaining the world (Coryn, 2006, p.1).” 
As opposed to assessment or evaluation, research focuses almost solely on contributing to a field or discipline of knowledge, rather than on making recommendations for bettering practice (namely, teaching/instruction) and, therefore, outcomes from it (namely, learning and development). Thus, the role of the assessment professional is nearly always more prescriptive than that of the researcher; in other words, the ethical assessment professional is required to suggest options for a course of action based on findings.
Further, as opposed to research, assessment is more likely to be constrained by considerations of time/resource limitations, and to be focused on “… utility, feasibility, propriety, and inclusion of stakeholders (Mathison, 2008).”

What is the difference between assessment and institutional research?

See above for the definition of assessment. “Institutional research is research conducted within an institution of higher education to provide information which supports institutional planning, policy formation and decision making” (Saupe, 1990). A variety of models exist for units of institutional research (IR) which can include IR functions such as research and planning of institutional resource allocation, evaluation and assessment activities, leadership in institutional data management and use, federal and state reporting.  
IDA+A performs research, statistical and predictive analysis, and reporting for campus leaders and decision makers in support of evidence-based planning, evaluation, and assessment.
As opposed to assessment, IR is an encompassing term that includes using institutional resources for the methodological inquiry into organizational structure, function, and operations.

Is there a minimum number of individuals needed to report across various demographics?

The minimum number depends on the proportion of individuals belonging to a demographic and/or to the total number of respondents given a certain demographic, descriptor or qualifier. To protect the confidentiality of individuals belonging to demographics that are under-represented in the responses to a survey or other data collection effort, IDA+A recommends erring on the side of caution by not reporting publicly on demographics when relatively few individuals (typically, anything between 4 and 10) can be counted or grouped within specific demographic, or set of demographics, and/or comprise the total number of respondents. When data may reveal instances of inequity or discrimination, results may be reported to those who need to be aware, even when the guidelines above are not met. Please consult with a member of IDA+A’s Assessment Team, if you are in doubt. 

Where can I find the most common annual survey questionnaires used at Purdue? 

First, we suggest that our Purdue colleagues check out our survey calendar. If you do not find the information you seek, please contact us to ask when or how often and how (i.e., what questions) a certain construct (e.g., hope, belonging, well-being) or topic (e.g., climate academic rigor, satisfaction with advising, value-added of attending Purdue) can be found. The list of available datasets is growing, so please check back from time to time to see what new resources are available. Researchers can access data in easy-to-use Tableau search screens, or full (deidentified) datasets in Excel, SPSS or other formats to facilitate their own analysis.

Where can I find an annual calendar of survey projects currently being administered across our campus?

The survey calendar page allows the Purdue community to view the dates of large surveys being administered to students, staff, faculty, or alumni. IDA+A encourages the campus community to review the calendar to avoid scheduling surveys at the same time as others addressed to the same group. 

How can I add a survey to the calendar?

To add a survey to the calendar, please fill out this form.

Are surveys at Purdue confidential?

Purdue University surveys are typically confidential and are completely voluntary- i.e., respondents have the choice to skip questions they are not inclined to answer or drop out/stop out of any data collection effort at any point in time. For more information, please visit the Survey Administration section of our website.

Do all survey projects have to be submitted to the IRB for review?

No. Whether an IRB application needs to be submitted is based on whether the proposed project meets the federal definition of research; it is not based on the research or data collection method.

Who decides whether an IRB application or protocol should be submitted?

Purdue’s Human Research Protection Program will advise personnel on whether a project meets the federal criteria requiring the submission of an application or protocol to our IRB. Generally, projects that use survey data for internal purposes only, without the intent to publish or present the data publicly, do not require submission of an application or protocol to our IRB.

What is accreditation? Why should a university be accredited?

Accreditation is a form of external validation by a set of subject matter experts (aka, peer reviewers)—in this way institutions of higher education and some of the programs of study within them are judged by an outside agency and its members. Accreditation is a voluntary process of self-reflection and peer review that helps institutions to identify opportunities and challenges throughout the university and its programs. Academic institutions and programs use accreditation to ensure that they are meeting established standards of educational quality.
There are two types of accreditation: Institutional or “regional” and specialized. With institutional—or regional—accreditation, evaluators examine a university as a whole. Purdue is accredited by The Higher Learning Commission of the North Central Association of Colleges and Schools (HLC).
Specialized, or professional, accreditors evaluate specific programs (e.g., Masters in Nursing, Bachelor of Science in Chemical Engineering, Bachelor of Arts in Art History ). Not dissimilar to the regional or institutional accreditation bodies, these agencies are evaluating the continuous improvement processes and assessment measures we have in place to ensure we are continually improving our curricula, and confirm what we’re teaching is relevant and valuable in the workplace, but within a particular area or program of study. Specialized accreditation requires that every aspect of a program is reviewed—courses, assignments, facilities, faculty, curriculum, and funding, to name a few.  
Accreditation, whether regional/institutional or specialized, is a multi-year process and requires a significant investment of time on the part of our faculty and staff. Purdue knows that this is time well spent, because it provides a measure of assurance for students, their families, and other stakeholders, that we are doing what we say we are doing and providing what we say we are providing—i.e., fulfilling our missions.

What role does IDA+A play in accreditation?

For our regional accreditation process, IDA+A team members serve on a multi-disciplinary HLC “Lean Team” with the task of gathering, confirming, and maintaining data throughout the university for various required accreditation activities (4-year reassurance, quality initiative, and reaccreditation) and other submissions or sharing of information (e.g., institutional data update). For specialized accreditation, we work with assessment professionals within a college to collect or share data specific to their reporting requirements (administration and staff information, faculty qualifications and course loads, salary, budget information, etc.) for their accredited program(s). Program review and accreditation is tracked on the External Academic Program Review/Accreditation dashboard (Purdue login required). We also offer our knowledge and expertise to inform their various assessment and accreditation protocols or activities.

Where should I direct questions or comments about Purdue’s HLC accreditation? 

The Office of the Provost oversees our institutional accreditation activities. Please direct questions related to Purdue’s Higher Learning Commission accreditation to the Accreditation Liaison Officer, Beth Fines.

When was Purdue last reviewed for accreditation?

Purdue’s most recent accreditation review by the Higher Learning Commission of the North Central Association of Colleges and Schools (HLC) was in October 2019. As a result, Purdue received formal notification of its continued 10-year, unrestricted, or open-pathway, accreditation . The lengthy process included a written self-study report with input from a large number of Purdue faculty and staff, and an extensive visit from an HLC external peer review team. Purdue has been accredited continually since 1913 and will be evaluated again in 2029-30.

What are predictive analytics?

Predictive analytics is the use of data, statistical algorithms and machine learning techniques to identify the likelihood of future outcomes based on historical data. The goal is to go beyond knowing what has happened to providing a best assessment of what will happen in the future.

What is PDAP?

PDAP stands for Purdue Data Analytics Platform.  It is comprised of two platforms:

• The Greenplum Database
• The High-Compute Research Platform Zeus

These platforms facilitate faculty research and cutting-edge data science projects.

What is Greenplum?

Greenplum is a massively parallel processing (MPP) distributed database designed for analytics. It serves as secondary storage for several datasets across campus, allowing IDA+A to quickly and easily combine disparate data sources together to complete novel projects.

What is Zeus?

Zeus is a high-compute machine with 4 NVIDIA A100 GPUs, 96 processors and 1 TB RAM. It is used for cutting-edge experimentation including Generative AI using Large Language Models (LLMs) as well as faculty research.

How does Purdue make Artificial Intelligence decisions and ensure that data is used ethically?

Any time artificial intelligence is being used to power decision making in a way that has potential downsides, IDA+A partners with the Purdue Data Ethics Committee to analyze, deliberate, and make recommendations about appropriate uses of data. More information is available on the Data Governance Committees’ webpage.

What types of data science projects does IDA+A do?

The data science team has a broad mandate. Our team has done work with academic units to predict student success, has worked with energy & utilities to help predict utility usage, worked with the registrar to build degree requirements as complex graphs, and more. If you have a data project with a predictive component, or that seems more novel or complicated than something the industry has done before, we can likely help in some way.

What data sources are available in PDAP?

The Greenplum database stores data from several sources.  Some of the heavily used data sources are:

• Student Systems
  Data from the Banner Student System pertaining to courses, instruction, student applications, admissions, grades, and profiles.
