On a dot plot each dot represents one occurrence of a value on a number line. The more dots stacked above a number, the more frequently that value occurs in the data set. The mean is the average value of dot. To determine the mean value of a dot plot, first count the total number of dots on the plot. Then, find the sum of the values that each dot represents. Finally, divide the sum of the values by the total number of dots.
