question 31

Short Answer

For questions below, use the following: A researcher wishes to find out if a speed-reading course increases reading speed. Sixteen subjects were randomly selected from the adult population and then randomly divided into two groups. Group A was given a speed-reading course, and then, because the interval scores were badly skewed, each subject was ranked according to reading speed. Their ranks were 1, 3, 4, 6, 8, 9, 10, 15. Group B received no training, and their ranks on the same test were 2, 5, 7, 11, 12, 13, 14, 16.
