The mean and median of the total box office receipts are significantly differ. Standard deviation is 33.79, range is 105.10 and interquartile range is 41.53. The mean and median of the production costs are significantly differ. Standard deviation is 3.89, range is 12.00 and interquartile range is 4.55. The mean and median of the total promotional costs are approximately the same. Standard deviation is 2.48, range is 7.20 and interquartile range is 7.15. The mean and median of the total book sales are approximately the same. Standard deviation is 5.17, range is 17.30 and interquartile range is 5.40. The standard deviation, range and interquartile ranges for all the variables indicated that there variation among the four variables is considerably low, when compared with their means.
