DOES DRAWING AN IMAGE HELP МЕМORY? Exercises 8.27 to 8.29 describe three different experiments investigating the effect of drawing on memory. In each experiment, participants were ran- domly divided into three groups and shown a list of 10 words to memorize. The response variable is the number of words participants are able to recall. For each experiment, construct an ANOVA table to assess the difference in mean word recall between the three groups and answer the following ques- tions. (a) Which method had the highest mean recall in the sample? Which had the lowest? (b) What is the F-statistic? (c) What is the p-value?
