Calculate both LSD and HSD for the two experiments in Exercise 3 of the previous chapter, using the harmonic mean of the three sample sizes as your value for n. What conclusions can you draw for each experiment? Use your values for LSD and HSD to compare the relative statistical power of these two procedures.

Data from Exercise 3(previous chapter)

For each of the following two experiments, calculate the means and variances for each group first, and then use those statistics to perform the ANOVA.

a. Can you reject the null hypothesis for Experiment 1? Display your results in an ANOVA summary table, and state the significance of your F ratio in a sentence, using the proper format. Include the value for eta squared.

b. Can you reject the null hypothesis for Experiment 2? Display your results in an ANOVA summary table, and state the significance of your F ratio in a sentence, using the proper format. Include an estimate of omega squared.
