t-Test for Independent Groups

After we press the Define Groups button, we will get this box. We need to insert M and F into the Group 1 and Group 2 boxes to tell the program that any subject with a M code (i.e., a male) should be assigned to Group 1 and any subject with an F code should be assigned to Group 2.
