AP Statistics
Final Project
As a final project students will design their own statistical project involving testing hypotheses in a Power
point presentation. Perform a small hypothesis test of your own choosing. Do either a one- or two-sample
test or a Chi Square Test. Presentations should be 5 -10 minutes long.
Introduction and Research Question (10 points)
1. Pose a question
2. State the population of interest that you wish to sample
3. A description of how you carried out your experiment/study. Comment on strengths and weaknesses.
Data Collection (20 points)
1. How did you collect your data.
2. If you are going to ask questions of people in your sample, state the questions. How will you handle responses
that do not fit into your predetermined categories?
3. Are you confident your sample represents your population? Why or why not?
4. Display all data in a table broken up into categories you want to compare.
Exploratory Data Analysis (25 points)
1. Include good data summaries (mean, standard deviation, 5 number summaries etc.)
2. Include graph(s) of your data and commentary on what it shows. Use a box-plot, stem plot, scatter plot,
histogram, pie chart, bar graph, etc. Graphs should show the comparisons between all relevant groups you are
comparing.
3. Give descriptions of statistics and graphs. (shape, outliers, center, spread, etc)
Inference Procedure (25 points)
1. State your null and alternate hypotheses clearly in words and mathematically.
2. State the significance level and sample size.
3. State the significance test you will use. Check appropriate conditions for your significance test.
4. Calculate the test statistic z, t, ². State the formula and show your work.
5. Calculate the P value. State the method used.
6. Decide to reject or fail to reject your null hypothesis.
7. Answer your research question based on your calculations.
8. Provide a confidence interval for the parameter of interest if appropriate.
Reflection (10 points)
1. Comment on the strengths and weaknesses of the project.
2. Were there possible sources of error (bias, lurking variables, etc.) and what were their effect on the data. How did
these sources of bias limit the validity of our conclusions?
Presentation (10 points)
1.

Power Point is well organized and clearly presented.
Supporting graphs and charts are displayed.
Clearly communicate your procedure, calculations, and conclusion.
Your delivery of the presentation is rehearsed, planned and well executed.
Be interesting and inspire us to listen.
Do not read off the Power Point verbatim.
Degree of Difficulty (5 points)
Due Friday, May 27th by 11:59 pm:
1. An electronic copy of your Power Point presentation. It must be turned in via email to Mrs.
Muhammad at lamuhammaf@cps.edu. A penalty of 10 point a day if late. It is the student’s
responsibility to make sure that this attachment can be opened on a school computer
