Take-Home Activity: Create a 6 slide PowerPoint presentation as if you were giving talk on the results of the study. 1. Title, your name. 2. Research question and hypotheses: State the research question (Research question should be stated as a question), null & alternative hypotheses. 3. Methods: Give your response (dependent) and your two explanatory (independent) variables and their levels of measurement, the statistical test you chose, the alpha level you will be using and whether 1- or 2-sided. 4. Results 1: Describe your data, this should include: who was included in the study (entire survey or selected county), the appropriate measures for the two explanatory variables you selected. Please provide the summary statistics for all of your variables (i.e. means or proportions). Also, provide bivariate analysis to compare your explanatory variables to the response variable (i.e. correlation or mean comparison by groups). Comment on the results of the statistical test comparing the multiple groups of the response variable and the correlation. Include the type of test used, the value of the test statistic, the associated p value, and decision about the null hypothesis. Variables Explanatory Variable 1 Explanatory Variable 2 Level 1 Level 2 ... Response variable Summary Statistics Mean (SD) N (%) N (%) ... Mean (SD) Correlation between VAR 1 and outcome is XXX (p-value?); The mean outcome in group 1 is M (SD), while in group 2 is M (SD),.., using appropriate statistical approach (two-sample test, or one-way ANOVA), the group difference is/not significant (statistics, df, pvalue). 5. Results 2: Describe the results from the multiple regression model. Comment on the results of the statistical test. Please include the type of test used, the value of the test statistic, the associated p value, and decision about the null hypothesis. Explanatory Variable 1 Explanatory Variable 2 (reference group is...) Coeffi Estimate 1 2 t XXX XXX p-value XXX XXX What test(s) you are using? What about the statistical decision (reject or not reject null)? 6. Conclusion: We found evidence that... or We did not find evidence that... (no numbers or pvalues).
