DAS is not PAS!!!

• In PAS
• The rows are individual institutions
• User defines the columns by selecting other IPEDS
  variables
• The DAS
• Is a table generator
• Which produces aggregated data
• The user creates or modifies table parameter
  files (TPFs) by tagging
• Row variables
• Column variables and specifying
• Spanner variables, Filters, etc.

12
The DAS Web Site

• The vehicle for public access to education survey
  data collected by the U.S. Department of
  Education.
• Comprehensive source for tables, findings, and
  reports generated by NCES researchers.
• Data Analysis System On Line (DASOL) enables
  users to generate their own tables.

Tables Library

• Includes tables from
• NEDRC Tables
• Analysis Reports Tables
• ED TABS
• IPEDS Tables (including Compendium and State
  tables)
• Search NCES Quick Tables

15
http//nces.ed.gov/dasol/
There are many tables available to you online
Take a few minutes to look through these
tablesthey may be handy in the future
16
These are tables that have not necessarily been
included in published reports. NCES keeps track
of requests from the field and makes the
information available to others through this
service.
17
Analysis Reports

• Includes links to the full text of reports and
  the tables, figures, and table parameter files
  (TPFs) used to produce the reports
• Published Reports
• Reports in Progress

Look!
18
The Tables and the TPFs from these reports are
also available for you to download.
TIP The TPFs can be modified to create similar
tables for a specific group of interest.

Well search for postsecondary tables with
degrees in the table title
You can also use DAS to access the Quick Tables
published by NCES
26
Many of these tables are based on IPEDS datafor
example, number of degrees conferred to Black,
non-Hispanics
27
Look at the structure of a DAS table
Table Title
Column variables average price of
attendance average tuition and fees
Row variable region
Spanner variable level of institution
Note Rows are repeated for each level of the
spanner variable.

Access Applications

• Access the DASOL Application at
• http//nces.ed.gov/dasol/
• To Create Tables

30
Return to the main menu at http//nces.ed.gov/daso
l/ and click To Create Tables. To Create
Correlations is not available for IPEDS data.
31
Postsecondary Institution Data is IPEDS data the
other categories reference data from other NCES
surveys
32
IPEDS data is available in DAS for 2002, 2003,
and 2004. This is adjudicated data that can be
used to generate national, regional, and state
totals and averages.
33

34
Alternatively, you can access the DAS
applications for specific datasets using the
pull-down menu.
35
IPEDS in DAS

• Generate totals and averages
• National
• Regional
• State
• With adjudicated IPEDS data
• 2004-05
• 2003-04
• 2002-03

36
Steps for Creating a Table

• Specify row variables
• Specify column variables
• Specify qualifying values, if necessary
• Run the resulting table parameter file (TPF)
• The process of selecting your variables is
• called tagging. A tag tells DASOL how to
• use each variable in building the table.

37
List of Variables

• Organizational Framework and Search Capabilities

38
Note the menu bar. Survey and year are specified.
Online Help is a great resource for learning to
use DAS Online!
These are the categories available for 2004.
More variables are available for earlier years,
and more will be added for 2004 as the
adjudication process is completed.

The directory tree structure of the variables
list expands to show the variables that are
stored under each of the major headings. A
plus sign indicates there are variables listed
under the heading. Once the heading is expanded
a minus sign indicates the list has been
expanded.

DAS Online Exercise 1

• The first exercise shows you how to create a
  simple table of total headcount enrollment by
  Carnegie Classification and save the table
  parameter file (TPF) to your drive.
• The top section of your report shows total
  headcount enrollment by Carnegie Classification,
  and the bottom section shows the number of
  schools in each classification.

• The second exercise shows you how to import
  and edit the TPF you just saved so you can group
  the Carnegie Classifications into fewer
  categories.
• This report has the same structure, but both
  sections reflect the categories just created.
