The place to go for

IPEDS data:

http://nces.ed.gov/ipeds


Session agenda

Session Agenda

  • Data availability and issues

  • Important data concepts

  • Review of Peer Analysis System

    • Basics

    • Advanced features

  • Research Questions with PAS

    • Average freshman tuition discount

    • Expenditure comparison

    • Schools offering a specific degree


Data available in the peer analysis system

Data Available in thePeer Analysis System

  • 1980, 1984, 1985 HEGIS data

  • 1986 – 2004 IPEDS data

  • Selected HEGIS data not in the PAS are available at through the International Archive of Education Data housed at the University of Michigan.


Availability caveats

Availability Caveats

  • Not all data are available for all years

  • New surveys have been added over time

  • Some data fields have been discontinued

  • New data fields have been added

  • Definitions may change


Ipeds peer analysis system advanced module

Data Availability by Year


Data issues

Data Issues

  • Changes in finance reporting standards began in 1997 and have been phased in over a period of time. Now, most privates use FASB and most publics use GASB. However, there is still great variability in Finance data that makes inter-institutional comparisons problematic.


More data issues

More Data Issues

  • Some data required in alternate years, but some schools submit for all years:

    • Enrollment by age: odd years

    • Residence of first-year students: even years

    • Fall staff: odd years

      Be very careful working with data from the years when submission is not required.


And more data issues

And More Data Issues…

  • Until submitting new variables is mandatory, not all schools submit data for them.

  • Continuing education is defined differently by different schools.

  • NCES began allowing schools to enter their own FTE values for 2002-03 data year


Important data concepts

Important Data Concepts

  • Collection year vs. data year

  • Imputation and perturbation

  • Release sequence of IPEDS data

  • Structure of IPEDS data files

  • Frequently used/derived variables


Ipeds peer analysis system advanced module

1. Collection Year vs. Data Year

  • Collection year:academic year in which the data are collected by NCES during the fall, winter, and spring collection cycle

  • Data year:academic year the data represent, which may be prior to the collection year


Status by survey component

Status by Survey Component


Master variables list selection

Master Variables List Selection

The surveys and the years for which data are available are displayed on the Master Variables List Selection screen.


2 disclosure protection

2. Disclosure Protection

  • NCES is required by law to protect against disclosure of individually identifiable information collected in the IPEDS surveys

  • Impacts four IPEDS data files:

    • Graduation Rates

    • Student Financial Aid

    • Salaries

    • Fall Staff


Perturbation

Perturbation

  • Random alteration of data in cells with small number of observations

  • Protects the confidentiality of individually identifiable data

  • Occurs during migration of data from data collection system to the PAS

  • It’s unpopular—but the alternative is data suppression


Data sharing

Data Sharing

  • Data that an institution puts into IPEDS

    • Belong to the institution

    • May be shared

    • BUT, may be subject to FERPA

  • Data IN the IPEDS data collection system

    • Technically belong to NCES

    • Are subject to NCES confidentiality requirements

    • May NOT be shared

  • Data in the IPEDS Peer Analysis System

    • Have been perturbed

    • Protect individually identifiable information

    • May be shared


Ipeds peer analysis system advanced module

This pop-up window precedes any data access. You must agree to the terms in order to proceed with your analysis.


Imputation

Imputation

  • IPEDS data are imputed for total nonresponse and item nonresponse

    • Various methods used such as prior year adjusted values, nearest neighbor, group means

  • Imputation allows files to be used for national totals

  • Imputed values appear on final data files

  • Web data input has dramatically reduced the need to impute data values


3 data release stages

3. Data Release Stages

  • Pre-release: login at collection level

    • Data are reviewed and perturbed

    • Locked institutions are migrated to PAS

    • Data available for peer comparisons only

  • Early release: login at institution level

    • All institutions are migrated to PAS

    • Data available for peer comparisons only

  • Final release: login at guest level

    • Data are imputed and fully adjudicated

    • No restrictions on data use


4 structure of ipeds data files

4. Structure of IPEDS Data Files

  • Single-record files contain one line of data for each institution—for example, data in the Institutional Characteristics survey

  • Multiple-record files contain several lines of data for each institution—for example, data by race/ethnicity and gender inthe Enrollment survey


Single record file

Single-Record File


Multiple record file

Multiple-Record File


Qualifying variables

Qualifying Variables

  • When choosing variables from multiple-record files, the user must first specify the qualifying variables

  • The user’s choice tells PAS which records to select for the analysis


Ipeds peer analysis system advanced module

For example, in order to select Hispanic students, you must specify which Hispanic students. All Hispanic students?

Full-time Hispanic students? Undergraduate Hispanic students?

Level of student is the qualifying variable that lets you to choose. Here, choose

Full-time students total and Part-time students total.


Ipeds peer analysis system advanced module

Then select Hispanic men and Hispanic women.


Ipeds peer analysis system advanced module

The resulting PAS file will contain a value for each possible combination:


5 frequently used derived variables

5. Frequently Used/Derived Variables

  • Permanent “calculated variables

    • frequently used “institution” variables, e.g.,total enrollment, tuition and fees

    • data feedback report variables

    • College Affordability Index variables

  • Developed by NCES from existing IPEDS survey variables

  • Available beginning in 2002

Review of strategies


Analysis strategy

Analysis Strategy

  • Select a group of colleges and universities

  • Identify variables for years of interest and retrieve those data for the group of schools

  • Generate reports useful for policy analysis, peer comparisons, assessment, administrative decision-making, etc.


3 steps to peer analysis

3 Steps to Peer Analysis:

1. Identify a LinchPin institution

  • the institution you want to compare with others

    2. Construct a comparison group

    3. Prepare your analysis

  • generate reports, files, statistics, graphs


Comparison group

Comparison Group

  • Three methods of construction

    • Select by name or UnitID

    • Select by variable (shared characteristics)

    • Auto peer group

  • Peer groups can be saved to your hard drive for later use as files with a ‘uid’ extension


Types of analyses reports stats

Types of Analyses = Reports & Stats

  • Ranking report

    • One variable, with values sorted high to low

  • Institutions Data report

    • Multiple variables, perhaps from multiple files

  • Statistical Summary report

    • Basic descriptive statistics, with optional graphs

  • Report Templates

    • Prepackaged formats

  • Forms Facsimile

    • Survey data, presented in survey grid format


Master variables list

Master Variables List

  • Stores all variables used in a session

  • Accessible through Main Menu  Session Summary

  • Lists can be saved to your hard drive with an .mvl extension


Calculated variables

Calculated Variables

  • Three types:

    • Summation

    • Difference

    • Ratio

  • Can be built from IPEDS variables

  • Can be built from calculated variables

  • Can be saved to your hard drive as part of a Master Variables List

Research question

Research Question

  • What is the average first-year tuition discount rate for private schools in California?

    Most private institutions allocate some of their own resources to fund scholarships to attract new students. In the aggregate, these scholarships reduce the institution’s average tuition.


Calculation strategy

Calculation Strategy

Michael Duggan and Rebecca Matthews developed the following strategy: Freshman discount rate is the ratio of institutional grant aid to gross tuition revenue for the full-time first-time cohort.


Variables required

Variables Required

  • For gross tuition revenue generated by new freshmen:

    • Tuition rate

    • Number of freshmen in cohort

  • For total institutional grant aid awarded to new freshmen:

    • Number of freshmen awarded institutional aid

    • Average amount of institutional aid awarded


Ipeds survey sources

IPEDS Survey Sources

Constraint:

The most recent financial aid data is 2003-04, so all variables should be selected for this year.


Define comparison group

Define Comparison Group

  • From Institutional Characteristics, 2003, add

    • State abbreviation

    • Sector of institution

  • To apply this exercise to public institutions, you would have to know the percentages of in-state and out-of-state students for each school.


Build master variables list

Build Master Variables List

  • From Institutional Characteristics and Student Charges, 2003, add:

    • Published in-state tuition and fees 2003-04 from Price of attendance of full-time, first-time undergraduate students (charges for full academic yr)


Ipeds peer analysis system advanced module

  • From Enrollments, 2003,from Total entering class: Fall 2003,add

    • Full-time first-time degree/certificate-seeking undergraduate (current years GRS cohort)


Ipeds peer analysis system advanced module

  • From Student Financial Aid, 2004,from Student counts and financial aid, academic year 2003-04,from Financial Aid: Full-Time First-Time Degree/Certificate-Seeking Undergraduates, add

    • Number receiving institutional grant aid

    • Average amount of institutional grant aid received


Run institutions data report

Run Institutions Data Report

  • Select Reports and Stats, Institutions Data Report

  • From your Master Variables List, select all four variables

  • Specify long variable names

  • Download your results in csv format and save as an Excel file

…and it looks like this


Do calculations in excel

Do Calculations in Excel

  • Total Tuition and Fees(tuition x number in freshman cohort)

  • Total Institutional Grant Aid(number receiving grant aid x average award)

  • Average Freshman Discount Rate(Institutional Grant Aid / Total Tuition & Fees)


Create an attractive report

Create an Attractive Report

  • Add a report title

  • Adjust column widths and column titles

  • Sort from high to low on average freshman discount rate


Ipeds peer analysis system advanced module

-Total Tuition Revenue

-Total Grant Aid

- Freshman Discount Rate

Add a title, modify the headings, and format the numbers. It’s a report!


Research questions

Research Questions

  • What percent of “core” expenditures (as defined by NCES) is represented by instruction?

  • Have these percentages changed between 2002 and 2004?

    Answer these questions for four-year public doctoral/research institutions in Georgia and Alabama.


Define comparison group1

Define Comparison Group

  • Add by Variable

  • From Institutional Characteristics, 2004, add

    • State abbreviation

    • Sector of institution

    • Carnegie Classification code

Add to master variables list

Add to Master Variables List

  • From Finance, 2004,from Frequently used financial indicators for all institutions: Fiscal year 2004, add

    • Core expenses, total dollar

      from Public institutions - GASB 34/35: Fiscal year 2004, add

    • Instruction - current year total


Ipeds peer analysis system advanced module

  • ‘Core expenses, total dollar’ must be calculated for 2002 and 2003. According to the info button for 2004, these are the components:


Ipeds peer analysis system advanced module

  • From Finance, 2002 and 2003,from Public institutions - GASB 34/35: Fiscal year 2002 and 2003, from Expenses and other deductions, add current year totals for those 11 variables:


Calculated variables1

Calculated Variables

  • Create two summation variables

    • Core Expenses 2003

    • Core Expenses 2002

      using the 11 components for each year

  • Create a ratio variable

    • Instruction as a Percent of Core, 2004

      • Instruction – current year total as numerator

      • Core Expenses for 2004 as denominator


Recursive calculated variables

Recursive Calculated Variables

  • Create two ratio variables:

    • Instruction as a Percent of Core, 2003

    • Instruction as a Percent of Core, 2002

      using the same technique

      Why would you create a recursive variable instead of doing the calculation in Excel?

      So you can save it in a Multiple Variables List for use in the future!


Ipeds peer analysis system advanced module

Check to see if the columns are in chronological order, and fix them if they aren’t.


Create an attractive report1

Create an Attractive Report

  • Add a report title

  • Adjust column widths and column titles

  • Order columns by year

  • Sort from high to low on ‘Instruction as a Percent of Core, 2002’

  • Create a graph to illustrate changes over three years


Research questions1

Research Questions

  • How many schools offer doctorates in Exercise Science?

  • How many doctorates in Exercise Science do they award?

    The Enrollment survey does not collect data by program, but Completions contains degrees awarded. Look at degrees awarded over a three-year period because not all schools with the program may award degrees every year.


Build master variables list1

Build Master Variables List

From 2003, 2004, 2005 Completions:

  • Qualifying variables:

    • CIP Code: 31.0505, Kinesiology and Exercise Science

    • Award Level: Doctor’s degree

    • First or Second major: First major

  • Variable:

    • Grand total


Comparison group strategy

Comparison Group Strategy

Because Exercise Science is a relatively small degree-producing program, you want to include in your sample all schools that awarded doctorates during a three-year period. That is, you want all schools that awarded doctorate in 2002-03 OR in 2003-04 OR in 2004-05, not just those that awarded doctorates in all three years—or only in 2004-05.


Define comparison group2
