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:
Conduct a one-way analysis of variance on these data.
Answer to relevant QuestionsWhat effect does smoking have on performance? Spilich, June, and Renner (1992) asked nonsmokers (NS), smokers who had delayed smoking for three hours (DS), and smokers who were actively smoking (AS) to perform a pattern ...Using the data from Exercise 16.25, (a) Calculate h2 and v2. (b) Why do the two estimates of the magnitude of effect in part (a) differ? (c) Calculate a measure of d^, using the most appropriate groups. In Exercise 16.7, For Exercise 17.15 use the protected t test to compare the Nonsmoking group to the other two groups in the Driving Simulation task. Describe a reasonable experiment in which the primary interest would be in the interaction effect.
