STATISTICS PROJECT

The detailed parts of the complete project are listed below. It is recommended that you print this and review the entire project.

Project, Part 1

This is the first part of a statistical study that you will be working on throughout the course. By the end of this project, you will have collected data and completed different types of statistical analyses. You will:

• Identify a topic and design the project.
• Identify how you will choose the sample for your project, including how you will minimize selection and participation bias.
• Compute the mean, median, mode, and mean absolute deviation.
• Calculate the variance and standard deviation for the project data and draw the distribution for the data.
• Construct a scatter diagram using two variables. Compute the correlation coefficient. Interpret the graph and value of the correlation coefficient.
• Summarize conclusions from your analysis.

Project, Part 2

Design the statistical study you will be conducting through the remainder of the class. Your study should include the following features:

• Determine the type of study you will use and the possible confounding variables (if using an experiment).
• Identify your treatment and control groups, and explain the need for these groups.
• Explain how your study avoids the placebo effect and the experimenter effect. Also add a note on the power of the placebo effect.
• Will your experiment be a Single- or Double-Blind experiment? Explain why.

Project, Part 3

In this part of the project, you need to accomplish the following tasks:

• Identify how you will choose the sample for your project.
• Identify how you will minimize selection and participation bias.
• Identify the possible sources of random, systematic, absolute, and relative error. If some types or errors don't apply to your study, explain why.

Project, Part 4

You have three tasks to complete for your project.

• Collect the data for your research project and assign bins for the data, if necessary, using the guidelines presented on pages 99-101 in your textbook.

· Using the data you collected for your project, compute the mean, median, mode, and mean absolute deviation.

· Calculate the variance and standard deviation for your project data. Draw the distribution for the data.

Project, Part 5

With the data you collected for your project, construct a scatter diagram using two variables. Compute the correlation coefficient. How do you interpret the graph and the value of the correlation coefficient?

TIP: Use the drawing tools available in MS Word (Select View, Toolbars, and Drawing).

Project, Part 6

Determine the "best-fit" line on the scatter diagram that you constructed for your project. Write a paragraph explaining why the line you chose was the "best fit."

Project, Part 7

Collect all the Project based assignments you have submitted over the past 4 weeks. Refer to the feedback from your Instructor, and organize your research study. Consider the following:

• You may make changes to your project, but these changes should be highlighted in the document.
• If applicable, make a note of the different types of errors (sampling error, type I and type II errors, etc.).
• Illustrate your conclusions in terms of confidence intervals, significance levels, etc.
