Interpret the summary statistics for associated variables for Descriptive Statistics (Tables)

An associated variable is a continuous variable that is grouped by categorical variables. In Minitab, you can display summary statistics for associated variables in a table.

At the bottom of each table, Minitab displays the Cell Contents, which indicates the statistics and their order in the cell. For summary statistics, you can display the mean, median, minimum, maximum, sum, standard deviation, data value, number of non-missing observations, number of missing observations, proportions of observations equal to a specific value, and proportions of observations between two numbers, for each associated variable.

This table contains statistical summaries for pulse rate, classified by gender. In each cell, Minitab displays the mean, minimum, maximum, standard deviation, number of observations, proportion of values that equal a specified value, and the proportion of values that are within a specified range of values. The columns of the table are as follows:
  • The first column contains the summarized pulse data for females.
  • The second column contains the summarized pulse data for males.
  • The third column contains the summarized pulse data for all study subjects.

For all the study subjects, the mean pulse rate is 73.14 beats per minute (bpm). The lowest value is 54 bpm, and the highest value is 100 bpm. The standard deviation is 10.75. The number of study subjects is 91 (35 females and 56 males). 5.495% of the pulse rates are exactly 74 bpm, and 32.97% of the pulse rates range from 70 to 80 bpm.
