Abstract
In addition to graphical summaries (Chapter 2), the primary features of a data set can be summarized through numerical indices. Measures of location or central tendency specify the “center” of a set of measurements. This chapter describes ways to use SPSS to obtain three common measures of location—the mode, the median, and the mean of a sample. For example, measures of location can be used to:
-
find the most common college major for a group of students;
-
find the midpoint of a set of body weights that divides the set in half;
-
calculate the average price of a gallon of gasoline in 1997;
-
find the percentage of 13-year-old students who have a home computer.
