Question

1. An older memory study by Eysenck (1974) compared the recall of older participants under one of 5 levels of processing of the learned material.  He demonstrated that when asked to perform a higher level of processing a list of words, participants showed better recall at a later time.  Eysenck also compared Younger and Older participants on their recall abilities when instructed that they should simply memorize the material for later recall.  The data on 10 participants in each group follow, where the DV is the number of items recalled.

Younger  21   19   17   15   22   16   22   22   18   21

Older      10   19   14    5   10   11   14   15   11   11

a. Conduct the analysis of variance comparing the means of these two groups.   Do this one by hand, including stating your hypotheses, Finding the critical F, and completing the summary table, so that you can compare your test statistic to your critical F.  

b. Then, interpret your results.

 

2. Another way to look at Eysenck's study is to compare four groups of participants.  One group consisted of Younger people instructed to use a Low level of processing.  A second group consisted of Younger people instructed to use a High level of processing.  The other two groups were Older participants instructed to use either Low or High processing.  The data follow:

Young/Low 8    6    4    6    7    6    5    7    9    7

Young/Hi 21    19    17    15    22    16    22    22    18    21  

Older/Lo 9    8    6    8    10    4    6    5    7    7

Older/Hi 10    19    14    5    10    11    14    15    11    11

a.  Calculating by hand, go through the same steps that you did for #1.  Be sure to interpret your results using  Corty's 4-point interpretation.

b. Hand-calculate HSD, and determine which (if any) groups are significantly different.

c. Enter these data into SPSS, and confirm your hand-calculated results.  Paste your SPSS summary table and Post-hoc table from SPSS here.  Then answer the following questions:

d. For the overall one-way ANOVA what is r2?

e. What does that mean?  Use the value for r2 in your answer to this question.

f. Which value represents the original Sum of Squared Deviations around the Grand Mean?

g. Which value represents the Sum of Squares explained by groups?
