Each of the four graphs below show a dotplot of data from three separate random samples. For each of the four graphs, indicate whether you think that the basic assumptions for single-factor ANOVA are plausible. Write a sentence or two justifying your answer. Graph 1 Graph 2 Graph 3 Graph 4 Sample 3 Sample 2 Sample 1

Step 1
- The populations from which the samples are drawn should be normally distributed. - The samples should have approximately equal variances (homogeneity of variance). - The samples should be independent. Show more…

The plot below on the left shows side-by-side boxplots of the raw data for each treatment group and on the right is the normal QQ plot for the residuals from a one-way ANOVA fit to the data. Which of these statements is the most appropriate? No assumptions appear to be violated. The residuals do not appear to be normally distributed. The groups appear to have quite different variances. The observations do not look to be independent.

Each of the following normal quantile plots illustrates a sample. In which cases is it reasonable to treat this as a sample from an approximately normal population? (More than one graph may be selected.)
