(Both by hand and in SPSS)
Suppose the low-self-esteem participants from Shrauger's (1972) audience study were brought back in 2010 to repeat the same cognitive task.The data still represents the number of errors made by each participant (3 participants in each condition).This time, assume the same 3 participants experience each of the 4 conditions:
Alone
With audience
Year
1972
8, 7, 2
12, 14, 11
2010
9, 6, 5
9, 6, 4
For the by-hand part, answer the following three questions: does there appear to be 1) a main effect of year, 2) a main effect of alone/audience, and 3) an interaction between the two? Show your work to answer whether these effects appear to exist.Then, let SPSS do the hypothesis tests to see if the effects really are significant.
Also, calculate the appropriate effect sizes for each of these three tests.
