Compute a one-way ANOVA, with α = .05.
Step 1: State your hypotheses in SYMBOLS. Step 2: Draw your distribution and shade in the critical region (remember that you have to compute df to find the CR). Step 3a: Calculate the test statistic. Step 4: Make a decision about your hypotheses. Step 5: Compute and interpret effect size

Means that do not share a letter are significantly different.
Thus we find that the pairs (sample 3,sample 1) and
(sample 2,sample 1) are significantly different.
Further, we provide a plot for clear viewing the significant
pair.
