Data Analysis System (DAS) - Generate Data Tables and Correlation Matrices

Generate analytical tables of data (percentages, means, and sums) and correlations matrices using datasets in the following categories:

• Postsecondary Institution Data
• Postsecondary Students
• Postsecondary Faculty
• High School Cohorts
• Early Childhood and Household Studies

Go to the Data Analysis System

Grouping institutions

Create group of institutions to be included in the table by specifying criteria. Examine groups of institutions (not individual schools) in terms of percentages, means, and sums.

Tables

In the Tables mode, the DAS system will produce a table of estimates, corresponding standard errors calculated by taking into account the complex sampling designs used in NCES surveys, and weighted sample sizes for the estimates.

Correlations

In the Correlations mode, the DAS will produce a correlation matrix that can be used for linear regression models. The design effects for each variable are included in the output. Since statistical procedures generally compute regression coefficients based on a simple random sample assumptions, the standard errors must be adjusted with the design effect to take into account the stratified sampling method used in NCES surveys.
