Data Set A is 50 numbers generated randomly with the constraint that the range be 1–100. Data Set B is the same Data Set A except the first column of numbers are smaller by 20, and the fifth column of numbers are larger by 20. The same pattern of difference exists between Data Sets B and C, and between Data Sets C and D. All data sets are normal according to Kolmogorov–Smirnov (p > 0.05) and Shapiro–Wilk (p > 0.05) statistics.
