Interpreting the results

Minitab displays the mean, standard deviation, and sample size of Height and Weight, classified by Gender and Activity. For example, the men with moderate activity level have a mean weight of 158.1 lbs, with standard deviation of 20.58 lbs. These values are based on 35 nonmissing observations. The column margins are the overall statistics for all the data. For example, the mean height of all the participants in your study is 68.73 inches.
