Generate a single correlation matrix which will allow you to test the null hypothesis of no relationship for all of the following pairs of variables from the General Social Survey:
Job satisfaction (JOBSAT1) and income (REALRINC)
Job satisfaction (JOBSAT1) and years of education (EDUC)
Income (REALRINC) and education (EDUC)
Days of poor mental health during the past 30 days (MNTLHLTH) and job satisfaction (JOBSAT1)
a. Create the correlation matrix.
b. Report the strength and direction of the Pearson’s r correlation coefficients for each pair of variables.
c. What other pairs of variables could be tested using this same correlation matrix?
