These exercises (15 in all) were written for instructors teaching an introductory class in statistics. They were written so each exercise is independent of the others and any one exercise can be used even if the other exercises are not used. These instructional exercises were originally written for SPSS. However, some colleges, including many community colleges, do not have a site license for SPSS. The cost of SPSS is often prohibitive, so I rewrote the exercises to run in SDA, an online statistical package written and maintained at UC Berkeley. SDA is freely available wherever you have an internet connection. I prepared a document to help you with SDA (Notes on Using SDA) which should answer some of your questions about SDA. These documents can be downloaded from the website. The data set used in this exercise is the 2014 General Social Survey. You have permission to use these exercises and to revise them to fit your needs. Each exercise has a set of keywords to give you a quick view of what is covered.
