Set up your hypotheses, Report your Hypotheses in narrative and symbolic form. Use a = 101 0 What is the Dependent Variable? What is the Independent Variable? I How many levels exist for the independent variable? 0 Perform the appropriate ANOVA. Present your results in an ANOVA Summary Table 0 Complete the Scheffe' Test if you find a Significant F . Compute the R2 If necessary 9. t is assumed that achievement test scores should be correlated with student's classroom performance. One would expect that students who consistently perform well in the classroom (tests, quizes, etc.) would also perform well on a standardized achievement test (0 - 100 with 100 indicating high achievement). A teacher decides to examine this hypothesis. At the end of the academic year, she computes a correlation between the students achievement test scores (she purposefully did not look at this data until after she submitted students grades) and the overall g.p.a. for each student computed over the entire year. The data for her class are provided below. Achievement G.P.A. `Achievemen G.P.A 1. Compute the correlation coefficient. t 2.
