SPSS Cumulative Assessment Instructions
The following research questions can be answered using 1 of the 5 tests you have learned so far:singlesample ttest, pairedsamples ttest, independentsamples ttest, oneway ANOVA, or twoway ANOVA. Use the information in the tables to construct your SPSS data file, just as you have been doing in Part 2 of each homework assignment. There is only 1 correct choice of analysis for each question. The assessment is openbook/opennotes.
For each problem involving a test of significance, your answer must include: A) the output and an appropriate graph from SPSS; B) a statistical statement (i.e., t(19) = 1.79, p = .049); and C) a sentence summarizing the results (i.e., “There was a significant difference between the two groups on the variable…” or “There was no significant difference…”).
For ANOVA problems: Report statistical findings and make statements for all main effects and interaction effects. Use the Fisher LSD test for any analyses requiring post hoc tests.
Submit this assignment by 11:59 p.m. (ET) on Monday of Module/Week 5.
