VARIABLES Subcommand (T-TEST command)

VARIABLES specifies the dependent variables to be tested in a one-sample or an independent-samples t test.

• VARIABLES can specify multiple variables, all of which must be numeric.
• When specified along with TESTVAL, the mean of all cases for each variable is compared with the specified value.
• When specified along with GROUPS, the means of two groups of cases defined by the GROUPS subcommand are compared.
• If both TESTVAL and GROUPS are specified, a one-sample test and an independent-samples test are performed on each variable.
