3. Calculate the test statistic t = 1.4533 4. Calculate the p-value 5. Calculate the effect size, Cohen's d, for this test. d̂ = 6. The results of this test indicate we have a... A. small to moderate B. large C. small D. moderate to large effect size, and... A. some evidence B. extremely strong evidence C. very strong evidence D. little evidence E. strong evidence that the null model is not compatible with our observed result.

A study found statistically significant results for a hypothesis tested with an independent-samples t-test. According to Cohen's convention, the author of the study reported her effect size for the test as medium. According to Cohen's convention, this convention is: a. 0.2. b. 0.8. c. 0.3. d. 0.5.
