Prior to beginning work on this assignment, review Chapter 10 in your course textbook, pages 109 to 120 in Chapter 7 of the
Jarman (2013) e-book, and the Week 2 Instructor Guidance.
Also, review The Chi-Square Test: Often Used and More Often Misinterpreted and The Chi-Square Test of Independence
articles.
Also, review the Two-Way Tables: Against All Odds – Inside Statistics, Chi-Square: Lecture 11, Chi-Square Tests: Crash Course Statistics #29, and Chi-Square Test for Association (Independence) | AP Statistics | Khan Academy videos; and review the How to Chi-Square Test and How to Interpret Chi-Squared web articles.
Also, complete the Week 2 learning activity and Week 2 weekly review.
Your instructor will post an announcement with the
scenario and data set for your Week 2 assignment. **SEE ATTACHED**
For the calculations in this assignment, you may use either Excel or the free VassarStats: Website for Statistical Computation
program online.
Instructions for performing a chi-square test of independence in Excel are included in Section 10.4 of the textbook,
accompanied by a screencast demonstrating the process in the electronic version.
Screencasts showing how to do a chi-square goodness-of-fit test and a chi-square test of independence in VassarStats are
included in the Week 2 learning activity, which you may review at any time.
For this test, you may prefer VassarStats because it is more automated than Excel. You also have the option of calculating the
chi-square manually, but if you choose this option, you must show your work and explain all of the steps taken to solve for the
chi-square value and to determine statistical significance.
In your paper, begin with a paragraph introducing the scenario and explaining why a chi-square test is needed for the situation. Then, address the following:
Identify which chi-square test you used and which program or procedure you used for the
analysis.
Describe the procedure you used to calculate the chi-square.
If using VassarStats, copy and paste the data entry area and output it into your paper.
If using Excel, submit the Excel spreadsheet separately and mention in your paper that the spreadsheet is attached. If using
hand calculations include a table showing the observed and expected frequencies, along with the row and column totals and
chi-square calculations.
Report the chi-square value, degrees of freedom, and the p
Explain how you determined the p Is the result statistically
significant?
If the test is a chi-square test of independence with a statistically significant result, report the effect size using
Cramér’s V.
Explain the meaning of the results in terms of the scenario.
Discuss any assumptions, limitations, and implications
associated with the situation and analysis.
Summarize the main points of the paper in a concluding paragraph.
The Chi-Square Data Analysis paper
Must be two to three double-spaced pages in length (not including title and references
pages) and formatted according to APA Style resource.
Must include a separate title page with the following:
Title of paper
Student’s name
University name
Course name and number
Instructor’s name
Date submitted
Must include an introduction and conclusion paragraph. Your introduction paragraph needs to end with a clear statement that
indicates the purpose of your paper, to report and explain your analysis of the scenario and data set.
Must use the course text; and Excel, VassarStats, or detailed documentation of hand calculations. Refer to Tables, Images, &
Appendices for assistance with formatting data and results tables.
Must document any information used from sources in APA Style guide.
Must include a separate references page that is formatted according to APA Style as outlined in the Writing Center.
