Statistics Project #7 Your task is to conduct a hypothesis test using real-life data. You will be working in groups for this project. The requirements for this assignment are as follows: Step 1: Planning- Type a project proposal answering the following questions. Write a brief paragraph or two answering the following questions. 1) What is your claim? Where does the “claim” come from? Is it common knowledge or something a friend has been claiming for quite some time that needs to be tested? 2) Are you testing a mean, proportion or standard deviation? 3) What is the significance of the study? (Why do it?) 4) Identify your population and sample size. 5) What sampling method will be used? When and where will you collect your data? 6) What level of significance will be used and why was it chosen? 7) Explain what test is being used (z, t, or χ2) and why. Will it be a right, left to twotailed test? 8) How will you display your data? Will you use a pie chart? Scatter plot? Histogram? Why did you choose this/these particular display(s)? 9) Are there any problems you may encounter when completing this assignment? Step 2: Data Collection – You will eventually collect and organize the data outside of class. Step 3: Hypothesis Test – Conduct the hypothesis test. Be sure to include your null and alternative hypothesis, critical value(s), sketch of sampling distribution, outcome and interpretation in the context of the claim. Step 4: Summary, Reflection and Error Analysis: After you have collected and analyzed your data, write a brief paragraph answering the following questions. • What conclusions or interpretations can be made as a result of your findings? • Identify any errors or flaws in the experiment. What would you change if you did it again? • What did you like and dislike about this project? Timeline: In-class workdays will be _______________ and ________________. Project proposal is due: _________________ Poster due: ________________ The audience for your display is SHS students who have not taken Statistics. It should include… • A “clean” copy of your planning paragraph(s) outlining the project and purpose • Typed tally sheet and Charts/Graphs displaying data • Neatly written and/or typed hypothesis test • Summary, Reflection and Error Analysis **This project is worth 30 points total – see grading guide on back for details


Project 7 Scoring Guide Planning – Graded separately based on completeness and depth. (10 points)

Data

Summary, Reflection and Error Analysis (x2)

Organization

Outstanding 5 points Data looks professional through the use of appropriate tables, tally sheets and other charts/graphs. Analysis includes conclusions or interpretations; errors or flaws in the experiment; any changes that would be made for future similar experiments; and likes/dislikes about the project

Average 3-4 points Data displayed, but lacks professional look and feel; or some information is not word processed

Below Average 0-2 points Incomplete (or no) data displayed; obviously no time taken in this area of the project

Analysis includes most (but not all) of the following: conclusions or interpretations; errors or flaws in the experiment; any changes that would be made for future similar experiments; and likes/dislikes about the project

Project displayed using tag board or other “visual” medium in a professionallooking manner.

Project displayed using tag board or other “visual” medium, but lacks professionalism (i.e. rough edges, organization, poor use of color, etc.)

Analysis is incomplete and includes less than half of the following: conclusions or interpretations; errors or flaws in the experiment; any changes that would be made for future similar experiments; and likes/dislikes about the project Project not displayed using tag board or other “visual” medium.
