The GSS is a national probability sample of adults in the United States conducted by the National Opinion Research Center (NORC). We’re going to use the General Social Survey (GSS) for this exercise. The mean is the sum of all the values divided by the number of values. The median is the middle value of a distribution. The mode is the most common value or values in a distribution. There are three commonly used measures of central tendency – the mode, median, and mean of a distribution. Central tendency refers to the center of the distribution. Sometimes this is referred to as univariate (one-variable) analysis. The exercise also gives you practice in using FREQUENCIES in PSPP.ĭata analysis always starts with describing variables one-at-a-time. The goal of this exercise is to explore measures of central tendency (mode, median, and mean) and dispersion (range, interquartile range, standard deviation, and variance). Extended notes for instructors (MS Word.Please contact the author for additional information. Included with this exercise (as separate files) are more detailed notes to the instructors and the PSPP syntax necessary to carry out the exercise. Please send a copy of any revision to the author. I prepared two documents to help you with PSPP – “ Notes on Using PSPP” and “ Differences between PSPP and SPSS” which should answer many of your questions about PSPP. You have permission to use this exercise and to revise it to fit your needs. This exercise uses FREQUENCIES in PSPP to explore measures of central tendency and dispersion. The data have been weighted according to the instructions from the National Opinion Research Center. Some of the variables in the GSS have been recoded to make them easier to use and some new variables have been created. Email: to the Instructor: The data set used in this exercise is gss14_subset_for_classes_STATISTICS_pspp.sav which is a subset of the 2014 General Social Survey.
