Document Summary
Distributions summarize the frequency of individual values or ranges of values for a variable. Measures of central tendency identify the most representative value of the distribution. Measures of dispersion indicate the variation around the measure of central tendency. The frequency of a particular category of interval is the number of times the category or interval is observed in the data. The distribution of a variable is the pattern of categorical . Shows the number of times a particular category or value appears. Cumulative freq. distribution shows the total number of accumulated cases up to a certain value. For the first row, the cumulative frequency is the same as the frequency. In each subsequent row, the cumulative frequency of the previous row is added to the frequency of the current row: report the percentage of cases in the category in the 4th column. To compute the percentage, divide the frequency by the total number of cases and multiply by 100.
