Based on these five study excerpts, I want you to do a few things for each study. FIRST, identify the study design (tell me if it is correlational or experimental). SECOND, if it is experimental, identify the independent variable. THIRD, if it is experimental, identify the dependent variables. FOURTH, tell me what statistical test the author ran and tell me how you know they ran that specific test (that is, what features of the results excerpt points to it being statistical test ABC rather than statistical test XYZ). FINALLY, piece together the null and alternative hypotheses for each study excerpt.
