2 National Center for Education Statistics (NCES) Mission – To make the data collected on education available to the public Provide indicators on the status and trends in education Report on the condition of education to Congress, state policymakers, educational practitioners, the media, and the public Assist states and school districts in improving their statistical systems Review and report on education in other nations

11 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.

13

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

15 Take a few minutes to look through these tablesthey may be handy in the future There are many tables available to you online

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.

20 Some of the E.D. TAB tables are based on IPEDS data

21 You can download anyor all! of the tables as Excel files Lets look at a hot-button issue

22 You can print this page or download it as an Excel file

23

24

25 You can also use DAS to access the Quick Tables published by NCES Well search for postsecondary tables with degrees in the table title

26 Many of these tables are based on IPEDS datafor example, number of degrees conferred to Black, non- Hispanics …

27 Column variables: average price of attendance average tuition and fees Column variables: average price of attendance average tuition and fees Row variable: region Row variable: region Spanner variable: level of institution Spanner variable: level of institution Note: Rows are repeated for each level of the spanner variable. Look at the structure of a DAS table: Table Title

29 Access Applications Access the DASOL Application at To Create Tables

30 Return to the main menu at and click To Create Tables. To Create Correlations is not available for IPEDS data. Return to the main menu at 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 This is adjudicated data that can be used to generate national, regional, and state totals and averages. IPEDS data is available in DAS for 2002, 2003, and This is adjudicated data that can be used to generate national, regional, and state totals and averages.

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

35 IPEDS in DAS IPEDS in DAS Generate totals and averages – National – Regional – State With adjudicated IPEDS data – – –

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

41 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.

47 Tagging Variables Rows, Columns, Spanners, Filters, and Qualifying Values

48 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.

49

50 Select a Tag TIP: There is a wealth of documentation included in the Variable Information tab of the Description Window.

51 Select a Tag

52 Remember what we are doing in this example is creating a simple table of total headcount enrollment by Carnegie Classification.

53 Select a Tag

54

55 SUM: The sum tag is only available in the IPEDS DAS. The Sum tag creates a column of sum estimates. Positive values and zero are included.

58 Confirm Input Your table title… # of columns… The specified rows… The specified column…

59 The top section of your table should look like this:

72 DAS Online Exercise #2 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.

74 Row Lump

75 In the modified table, the schools are grouped per your specification.

76 User Help Center Tutorials Help with Tags T-test Tool Technical Assistance

77 Online Help is divided into four sections Online Help is divided into four sections IMPORTANT! All new users should start with the tutorial! DAS is very different from the other tools weve reviewed. IMPORTANT! All new users should start with the tutorial! DAS is very different from the other tools weve reviewed.
