Then use the runs test to determine whether the results appear to be random. 2.In-class activity Use the existing seating arrangement in your class and apply the runs test to determine whether the students are arranged randomly according to gender. After recording the seating arrangement, analysis can be done in subgroups of three or four students. 3.In-class activity Divide into groups of 8 to 12 people. For each group member, measure his or her height and measure his or her arm span. For the arm span, the subject should stand with arms extended, like the wings on an airplane. Divide the following tasks among subgroups of three or four people. a. Use rank correlation with the paired sample data to determine whether there is a correlation between height and arm span. b. Use the sign test to test for a difference between the two variables. c. Use the Wilcoxon signed-ranks test to test for a difference between the two variables. 4.In-class activity Do Activity 3 using pulse rate instead of arm span. Measure pulse rates by counting the number of heartbeats in 1 min.
