The following data are from an independent-measures study comparing two treatment conditions. a. Use an independent-measures t test with α = .05 to determine whether there is a significant mean difference between the two treatments. b. Use an ANOVA with α = .05 to determine whether there is a significant mean difference between the two treatments. You should find that F = t 2 .
