Using a = .05, what is your conclusion? Three admission test preparation programs are being evaluated. The scores obtained by a sample of 20 people who used the programs provided the following data. Use the Kruskal- Wallis test to determine whether there is a significant difference among the three test prepa- ration programs. Use a = .05.
