question 5

Multiple Choice

A researcher wanted to see the effects of different learning strategies. A control group simply read the book Discovering Statistics (Book) , a second group read the book and completed the 'end of chapter exercises' (Book & Exercises) , and a third group read the book, did the end of chapter exercises and also completed the web materials (All Activities) . The researcher predicted that the 'all activities' and 'book and exercises' groups would perform better than the book group on a subsequent test, but that the 'book and exercises' group would perform worse than the 'all activities' group. Which coding scheme would test these hypotheses in a set of planned comparisons? (Hint: The sum of weights for a comparison should be zero. If you add up the weights for a given contrast the result should be zero.)
