You have been given two non - SPSS data sets to import in to SPSS and process:
a. Data set: Import the Excel file Ch 14 - Exercise 04A.xls in to SPSS (This Excel file has the variable names Group and Score on the top row.)
Codebook

Variable: Group
Definition: Group assignment
Type: Categorical (1 = Control, 2 = Treatment)
