Complex Samples Descriptives
The Complex Samples Descriptives procedure displays univariate summary statistics for several variables. Optionally, you can request statistics by subgroups, defined by one or more categorical variables.
Example. Using the Complex Samples Descriptives procedure, you can obtain univariate descriptive statistics for the activity levels of U.S. citizens, based on the results of the National Health Interview Survey (NHIS) and with an appropriate analysis plan for this
Statistics. The procedure produces means and sums, plus t tests, standard errors, confidence intervals, coefficients of 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.
