Complex Samples Descriptives
The Complex Samples Descriptives procedure displays univariate summary statisticsfor several
variables. Optionally, you can request statisticsby subgroups, defined by one or more categorical
variables.
Example. Using the Complex Samples Descriptives procedure, you can obtainunivariate
descriptive statisticsfor the activity levels of U.S. citizens, based on the results of the National
Health InterviewSurvey (NHIS) and with an appropriate analysis plan for this public-use data.
Statistics. The procedure produces means and sums, plus ttests, standard errors, confidence
intervals, coefficientsof variation, unweighted counts, population sizes, design effects, and square
roots of design effects for each estimate.
Data. Measures should be scale variables. Subpopulation variables can be string or numeric
but should be categorical.
Assumptions. The cases in the data file represent a sample from a complex design that should
be analyzed according to the specifications in the file selected in the Complex Samples Plan
dialog box.
