Skewness and the Mean, Median, and Mode · Example 1
Statistics are used to compare and sometimes identify authors. The following lists shows a simple random sample that compares the letter counts for three authors.
Terry: 7; 9; 3; 3; 3; 4; 1; 3; 2; 2
Davis: 3; 3; 3; 4; 1; 4; 3; 2; 3; 1
Maris: 2; 3; 4; 4; 4; 6; 6; 6; 8; 3
(a) Make a dot plot for the three authors and compare the shapes.
(b) Calculate the mean for each.
(c) Calculate the median for each.
(d) Describe any pattern you notice between the shape and the measures of center.
