Your task is to enter this data into an SPSS data file such that each column represents a variable and each row represents an individual person. Please make sure that you treat Role and Sex as nominal variables and Alcohol Use and Marijuana Use as scale variables. After you complete data entry please double check all values. Any error that you make at this stage will carry over to procedures that you perform later. You should have 32 rows in the data file each representing a sample participant.
