The following data are from an independent-measures experiment comparing the effects insomnia treatments on the amount of sleep participants acquire. The data below show the number of hours a participant slept in a single night.

using the repeated measures anova 1) The following data were collected from a repeated-measures study investigating the effects of 4 treatment conditions on test performance. Determine if there are any significant differences among the four treatments. State the null hypothesis. If you determine a significant treatment effect, use Tukey's HSD test (overall a = .05) to determine which treatments differ from which other treatments. Also, compute the percentage of variance explained by the treatment effect (12). Conclude with an appropriate...
