question 14

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 and exercises) , and a third group read the book, did the end of chapter examples 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 do worse than the all activities group. Which coding scheme would test these hypotheses in a set of planned comparisons?
