Task 1: To test how different teaching methods affected students’ knowledge I took three statistics courses where I taught the same material. For one course I wandered around with a large cane and beat anyone who asked daft questions or got questions wrong (punish). In the second I encouraged students to discuss things that they found difficult and gave anyone working hard a nice sweet

(reward). For the final course I remained indifferent and neither punished nor rewarded students’

efforts (indifferent). As the dependent measure I took the students’ percentage exam marks. The data are in the file Teach.sav. Carry out a one-way ANOVA and use planned comparisons to test the hypotheses that: (1) reward results in better exam results than either punishment or indifference; and (2) indifference will lead to significantly better exam results than punishment. ②
