t-Test for Independent Samples, by Variables

Creates t-test for independent samples, treating each column in the data file (variable) as an independent sample or group. T-tests are computed for all continuous dependent variables vs. all continuous predictors; if no continuous predictors are specified, t-tests are computed for all pairs of variables in the list of continuous dependent variables. Optionally, the Brown and Forsythe homogeneity of variances tests and categorized box-whiskers and normal probability plots are also computed (Levene's test for homogeneity of variances is computed by default).

Element Name Description
General
Box and whiskers Plot Creates box and whiskers plots for each variable (group).
Brown and Forsythe test Creates Brown-Forsythe test of homogeneity of variances.
p for highlighting results The default p-value for highlighting is .05; significant t-tests with p less than or equal this value will be shown in the highlight color in the results spreadsheets.
