the following data are from an experiment comparing three different treatment conditions: A: 0 2 1 5 2 B: 1 5 2 4 8 C: 2 5 6 9 8
a. if the experiment uses an independent measures design, can the researcher conclude that the treatments are significantly different? test at the .05 level of significance. b. if the experiment is done with a repeated measures design, should the researcher conclude that the treatments are significantly different? test with .05 alpha again. c. explain why the analyses in parts a and b lead to different conclusions.
