MTH 2310 – Project 2 Our second project will be one case but with multiple parts. How confident are we when we must make decisions based on data. We have been talking about sampling and then using that data to predict something about the population but big could our possible misjudgment be? This case is again about donor profiles and I chose it because we have all had experience with being asked to contribute to various organizations. We either have donated to an organization or decided against donating for various reasons. We know how people make decisions about whether to donate or not based on social, financial and personal reasons. Use your knowledge and experience to help you analyze this case along with the statistical tools available to you. Make sure you follow the process of analysis that our authors use in the textbook. (Process = Plan, Do, and Report) (The accompanying rubric with this project will tell you what I will be looking for as I correct the cases.) In our case study about donor profiles, we will look at the various issues that might influence people when they consider donating to a campaign. We can’t see the social and cultural reasons but we can analyze the results based on our knowledge of what might influence their donations. For example, raising children can be expensive so there may not be extra dollars to donate to a campaign. Wealth or owning a home may also allow people to feel they have the discretionary income that allows them to donate to a campaign. Read the case study, answer the questions they have asked, analyze the data using StatCrunch and then write a professional report based on my criteria. Case Study chapter 12 p. 349: Donor Profiles. Note: data set for this case is found at the StatCrunch tab in MyStatLab. Go to StatCrunch on the left side tab and click on it. You will then see a screen that says “View the data sets from your textbook in StatCrunch.” Click on the link which will take you to the list of chapters. Click on Ch. 12 for the data set for the case. Use the rubric to guide you in analyzing the data and answering the questions asked by the case. We will be using confidence intervals when comparing the data so make sure you clearly state what they are. You will want to use the correct language (Ex. We are 95% confident the average donation is between …..) when you write your report.

Possible Your

points Project is organized using the process – separate one for each case

Plan 10 • Objective is clearly defined • Introduction and background well written. Introductory paragraph is clearly

stated, has a sharp, distinct focus and enhances the impact of the report

Do 20 • Patterns in data identified and related to case study questions. Outliers are

identified if they exist. • Appropriate statistical techniques used for analyzing data and identifying the

center, shape and spread. • Graphs are clear, complete, concise, with context labeled

Report 10 • Conclusion well written. Concluding paragraph summarizes and draws a
