Application of the Pearson Correlation and Chi-Square Test
Start Date & Time Due Date & Time Points Jul 7, 2022, 12:00 AM Jul 13, 2022, 11:59 PM 120

The chi-square test of independence is used to determine whether two or more samples of cases differ on a nominal level variable. A Pearson correlation is used to determine the relationship between two continuous variables. Both the chi-square test of independence and correlation are widely used in the analysis of public

health data.

The purpose of this assignment is to practice calculating and interpreting the Pearson correlation coefficient and a chi-square test of independence. After analyzing the data, communicate the results in a PowerPoint presentation. Refer to the Using and Interpreting Statistics: A Practical Text for the Behavioral, Social, and Health Sciences textbook and instructional videos for assistance completing this assignment.

Part 1

Use SPSS and the Topic 2 “Health Behavior Data Set” and complete the following:
Conduct a Pearson correlation to determine the relationship between age and annual income.
Conduct a chi-square test to determine the relationship between sex and smoking status.
Export the SPSS output for the Pearson correlation and chi-square tests.
Part 2

Create an 8-10 slide PowerPoint to discuss the findings for either the chi-square or correlation findings. For the presentation of your PowerPoint, use Loom to create a voice-over or a video. Refer to the topic resources for additional guidance on recording your presentation with Loom. Include an additional slide for the Loom link at the beginning, and an additional slide for references at the end.
