Exercises 57 and 58 refer to the mode of a data set. The mode of a data set is the data point that occurs with the highest frequency. When there are several data points (or categories) tied for the most frequent, each of them is a mode, but if all data points have the same frequency, rather than say that every data point is a mode, it is customary to say that there is no mode. 1. Find the mode of the data set given by Table 15-20 ( Exercise 30 ). 2. Find the mode of the data set given by Fig. 15-15 (Exercises 11 and 12). Table 15-20 shows ages of the firefighters in the Cleansburg fire department.

Solution Summary: The author explains that the mode of a data set is the data point that occurs with the highest frequency. If all data points have the same frequency, it is customary to say that there is no mode.
