Another way to look at the Eysenck study mentioned in Exercise 16.1 is to compare four groups of participants. One group consisted of Younger participants who were presented the words to be recalled in a condition that elicited a Low level of processing. A second group consisted of Younger participants who were given a task requiring the Highest level of processing

(as in Exercise 16.1). The two other groups were Older participants who were given tasks requiring either Low or High levels of processing. The data follow:

Younger/Low 8 6 4 6 7 6 5 7 9 7 Younger/Hi 21 19 17 15 22 16 22 22 18 21 Older/Low 9 8 6 8 10 4 6 5 7 7 Older/Hi 10 19 14 5 10 11 14 15 11 11 Conduct a one-way analysis of variance on these data.
