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.
