Check out the frequency distributions for two treatment groups: Treatment 1 Treatment 2O n = 9 M= 8 n = 9 M = 13 s = 1.22 s = 1.22 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 a. Write a table with observations for these samples. b. Using the table, explain (calculate) where the S=1.22 comes from Conduct a two-tailed comparison of the two groups with a=.05. Please с. remember to state your hypothesis. Now look at: Treatment 1 O Treatment 2 n = 9 M = 8 n = 9 М- 13 s = 6.65 S = 6.65 0 1 2 3 4 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 d. Write a table with observations for these samples. e. Using the table, explain (calculate) where the S=6.65 comes from f. Conduct a two-tailed comparison of the two groups with a=.05. g. What changed between [a-c] and [d-f]? what impact did it have?
