Appendix BPractice Exercise Datasets
Practice Dataset 1
You have conducted a study in which you collected data from 23 participants. You asked each subject to indicate his or her sex (SEX), age (AGE), and marital status (MARITAL). You gave each subject a test to measure mathematics skills (SKILL), where the higher scores indicated a higher skill level. The data are presented below. Note that you will have to code the variables SEX and MARITAL and also indicate that they are measured on a nominal scale.
This example assumes students code SEX as 1 = M, 2 = F and MARITAL as 1 = Single, 2 = Married, 3 = Divorced.
