Description
Correlational Analysis
Using the attached survey, perform one analysis (i.e., Part A or B) using Pearson correlation and the other (i.e., Part A or B) using Spearman correlation. Determine the appropriate test for each relationship, and then proceed with your analyses. (The sample is 575 adults from River Forest, IL in the data. The population is all adults in River Forest, IL.)
Part A
Assess the relationship between the years of school completed (variable name = ducfnbsp;and the years of school completed by the mother (variable name = aeducn
Part B
Assess the relationship between the highest degree earned (variable name = %greefnbsp;and the stress level associated with work (variable name = ôressn

Mean and SD for each interval or ratio variable
come from the descriptive statistics portion of your
analysis. (For ordinal variables, just report the
median, e.g., Median = moderate). Also, coefficient
of determination is not reported in Spearman test
results.
