Description

Allows to create a table with different comparison of independent samples tests.

Required input

Comparison of independent samples - table

  • Variables: select the variables of interest in the top left box and next click the right arrow button to move the selection to the Selected variables list.
  • Filter for group 1 and Filter for group 2: the filters used to identify the two groups in which the selected variables must be compared.

    For example:

    Filter for group 1: TREATMENT="A"
    Filter for group 2: TREATMENT="B"

    Differences will be calculated as Group2-Group1.

    Caveat: the two filters must define distinct groups so that the same case is not included in the two samples.

  • Options: select Independent samples t-test (parametric) or the Mann-Whitney test (non-parametric).

Results

The program creates a table with the results of the selected test for each variable.
