MAT 300 Final Project Guidelines and Grading Guide

MAT 300 Final Project Guidelines and Grading GuideOverviewThe final project for this course is the creation of a statistical regression report. Based on the knowledge obtained in this course and previous coursework, you will examine the methodology used in building and performing regression diagnostics. You must select a statistical data source withapproval of your instructor. You must collect data, perform regression diagnostics, and determine the most appropriate set of predictors. The projectis divided into two milestones, which will be submitted at various points throughout the course to scaffold learning and ensure quality finalsubmissions. These milestones will be submitted in Module Three and Module Seven.OutcomesTo successfully complete this project, you will be expected to apply what you have learned in this course and should include several of the followingcourse outcomes:1. Construct multiple regression models, including first-order, second-order, and interaction models with both quantitative and qualitativevariables2. Assess whether a multiple regression model fits the sample data3. Implement regression analysis in real-world problems from engineering, sociology, psychology, science, or business4. Identify potential problems one may encounter when conducting regression analysis5. Demonstrate how residuals may be used to detect departures from model assumptionsMain ElementsIn the Final Project you will build and perform regression diagnostics on several models in order to determine the most appropriate set of predictorsand subsequently the most appropriate model. You must choose a topic of interest drawn from real-life experiences. You must collect data for thisproject and complete the following:Identify your variables, and categorize your response and predictors (qualitative and quantitative predictors).You must produce a scatterplot of the outcome variable versus each of the predictors.Conduct a first-order main effects model.Conduct an analysis of the model using regression diagnostics to determine whether the model is appropriate.Determine which additional terms (higher-order or interaction) should be included. You may go through several iterations of this processbefore you decide on your final model. Your final model must have at least one quantitative variable and one qualitative variable.Perform a nested F-test on your final model and a reduced model of your choice to show that the final model is the better one.Use your findings from the above model building and resulting analysis and write a paper summarizing your findings. Include relevant Minitab output(charts, graphs, regression results) in your statistical regression report. Refer to module content and the case studies in your text for additionalresources. Your paper must including the following parts:I.Introduction: Include your topic, your variables, an overall description of your data, the means of collecting data, and what you hope toachieve in your findings. Include any predictions as needed.II.Regression Model Building: Describe the results of the model you built. You must include the following information about both the firstorder main effects model and the final model:A scatterplot of the outcome vs. predictor variablesThe model equation in general formThe complete regression output from Minitab including any unusual predictorsA written explanation of why the model was/was not chosen (i.e., why those predictors were selected)The R2 value and its interpretationRegression diagnostics and your impression of themThe interpretation of each of the coefficients included in the final modelIII.Testing Model and Comparison of Models: Looking at your variables, only include those variables that are necessary. Conduct a reducedmodel as needed. Perform a nested model F-test on your final model compared to the researcher’s suggested model. Explain why theoutcome of this test shows that your model is the more appropriate one. Compare and contrast the original model and the final model anddiscuss the strengths or weaknesses of both based on R2 and the regression diagnostics. Also comment on the importance of an iterativemodel-building process. Particularly pay attention to the reasons why it is imperative that each model built is carefully examined. What arethe implications of just using the first model built?IV.Conclusion: Interpret your results in context of your topic.MilestonesMilestone One: Topic & Introduction DueIn Task 3-5, you will submit your topic and Introduction for instructor approval. This is non-graded milestone for formative feedback only.Milestone Two: Final Project: SubmitIn Task 7-3, you will submit your final project for review. This will be graded using the below rubric.
