Exercises for an Introductory Statistics Course Using SDA Edward Nelson, California State University, Fresno Preface These exercises were written for introductory statistics and research methods courses although they could be used in any class that has a quantitative component. They could also be used by individuals who want practice with the various statistical procedures. The exercises do not discuss all aspects of the statistics covered nor do they describe how to compute most of these statistics. This is the third in a series of exercises for statistics and methods courses. The first set uses SPSS while the second set uses PSPP. These two sets of exercises can be found on the Social Science Research and Instructional Council’s website . This series uses SDA (Survey Documentation and Analysis) which is an online statistical package written by the Survey Methods Program at UC Berkeley. SDA can be used without cost wherever one has an internet connection. Students can be shown how to use SDA in approximately ten minutes making it unnecessary to spend valuable class time learning how to use a statistical package. There is also an extensive help menu available to users of SDA. The data set used in this series of exercises is the General Social Survey’s 2018 Cumulative Data File (1972 to 2018) which is available without cost by clicking here . For these exercises we will only be using the 2018 General Social Survey. The exercises show students how to select the 2018 survey from the cumulative data set. A weight variable is automatically applied to the data so it better represents the population from which is sample was selected. The General Social Survey is a large, national probability sample of adults (18 years and older) living in the United States conducted by the National Opinion Research Center (NORC) at the University of Chicago. The GSS started in 1972 and was conducted annually through 1994 and biannually since then.
