Question:
1) Describe in your own words what type of research situations call for a researcher to use an ANOVA analysis.
2a) Use the Compare Means function (AnalyzeCompare MeansMeans) to compare the means of the threeSoundconditions onAnxietyandPerformance.
2b) Based on these results, on which variable does it most appear there might be significant differences based on theSoundcondition?
3a) Conduct a one-way ANOVA on bothAnxietyandPerformanceusingSoundas the independent variable. That is, conduct two separate one-way ANOVAs, one withAnxietyas the dependent variable and one withPerformanceas the dependent variable.
3b) Based on these results, were either of your ANOVAs significant? How can you tell? Use a cutoff level of .05 for your decision.
4a) Remember that in a one-way ANOVA, we are only looking at the impact of one variable on the dependent variable. Factorial ANOVAs, on the other hand, assess the impact of multiple independent variables. Conduct a factorial ANOVA on Performance using bothSoundandExperienceas independent variables. Be sure to choose the option to view the estimated marginal means forall ofyour main effects and interactionsthis will allow you to more easily interpret the results.
4b) Write the results of the ANOVA. For help, refer tothis document.
