Determine a topic for a survey and have it approved by the instructor. Ideas for your project can be found at the end of the chapters in the activity section. Pick a topic that is of interest to you. The topic should be such that you can obtain a sample of the appropriate size, statistical measures can be calculated, a hypothesis can be tested, and your topic has a related second variable in which to test correlation. The hypothesis should be developed early on in the process of completing this project.
The final project should be narrative in structure and should include all statistical calculations with complete explanations of how the statistical measures apply to your data. Data must be reported and all statistical measures completed on statistical software must be included. Use your textbook as a reference to give detailed explanations as you analyze your data. The project should be typed and presented in a manner fitting a final paper/project. You will be scored on completion of all parts listed below, detailed explanation showing understanding of statistical measures, and presentation.

Your project should include:

• Description of survey or collection of data
• How your data was collected including the source of your data
• Record your data into Statdisk or Excel
• Find the mean, median, mode, standard deviation, and variance. Analyze and explain why these statistical measures are important and how they apply to your data.
• Determine a confidence interval for the population proportion or mean
• Develop a hypothesis about your data in your sample. Test that hypothesis and report your conclusion.
• Use a .05 significance level to test for a linear correlation between two variables chosen
• Summarize your survey and the statistical measures you calculated.
