Chapter 11
Frequencies
In the chapter Examining Summary Statistics for Individual Variables, there is an
example showing a frequency table and a bar chart. In that example, the Frequencies
procedure was used to analyze the variables Owns PDA (ownpda) and Owns TV
(owntv), both of which are categorical variables having only two values. If the
variable that you want to analyze is a scale (interval, ratio) variable, you can use the
Frequencies procedure to generate summary statistics and a histogram. A histogram
is a chart that shows the number of cases in each of several groups. This example will
use Frequencies to analyze the variable Years with current employer (employ).
