From the states data set, get the descriptive statistics for the violent crime rate. For this assignment, you will need the mean, standard deviation, five-number summary (minimum, 25th percentile, median, 75th percentile, maximum), and interquartile range. Submit all answers as whole numbers--no decimal points. If you have to calculate the interquartile range by hand, you may calculate it using whole numbers as the 25th and 75 percentile. How would i calculate this?
