Question

Use the appropriate statistical test (i.e., either parametric or nonparametric) to answer each of the five questions using the EXAM2_DIG SPSS dataset. Remember to (1) report the statistical test value, df and p-value at the end of your one-sentence write-up, and (2) describe the relationship (even if non-significant) by reporting IV group means/sd, percents, or mean ranks. (NOTE: I do not need to see the SPSS output.) (12 points)
