  Statistics Through Applications, Chapter 2.1, Problem 2.24E , additional homework tip 3

By seeing the dot plot centre is at 11 and 1st quartile and 3rd quartile are 9 and 22.5 respectively. Inter quartile range is 13.5 and the minimum and maximum values are 0 and 90 respectively so the spread of the data is between 0 and 90 and the mode which is 9 because of highest frequency of the number. Five outliers are there and distribution is positive skewed or right skewed.
