Requirements for First Statistical Analysis Report

Due March 21

Use the same continuous outcome variable for all analyses.

You need a minimum of

two categorical predictors

two continuous predictors

A major proportion of your grade will depend on the accuracy, thoroughness, and clarity of your discussions.

Introduction	Brief description of where your data came from Definitions of the variables being used.
Factorial ANOVA	Two factorial ANOVAs Requires a continuous outcome and two categorical predictors. Discuss the assumptions you are making and provide evidence of whether they are valid. Graph main effects and interaction. Interpret the results. Include appropriate multiple comparisons if necessary.
Multiple Regression	Use the same continous outcome and the same set of two or more continuous predictors for both analyses. All-inclusive multiple regression Discuss results including consideration of assumptions and multicollinearity Stepwise multiple regression Provide a complete discussion of results at each step
Analysis of Covariance	Use one categorical predictor and one continuous predictor. (Select from the most promising variables in the prior two analyses.) Discuss and graph the results. Contrast your results to an ANOVA that does not use the covariate. Contrast your results to a simple linear regression that only uses the covariate.
General Linear Model	Repeat the ANCOVA analysis above as a GLM analysis that includes interaction. Discuss and graph the results. Contrast your results to the previous analyses.
Summary	Discuss what did and what did not influence your outcome variable. Among the analyses conducted, which seem to be the most appropriate and useful? A major proportion of your grade will depend on the accuracy, thoroughness, and clarity of your discussions.
