Write a paragraph reporting the following correlation matrix: Dependent variable is “Should the government reduce income differences,” 1=not at all…7=government should be involved. Independent variables are: “Blacks shouldn’t push where they are not wanted,” 1=strongly agree…4=strongly disagree, and political viewpoint where 1=extremely liberal, …, 7=extremely conservative. Calculate r2 values. Which variable mattered most in predicting attitudes about government involvement in reducing inequality?

Correlation between government reduce income differences and Blacks shouldn’t push where they are not wanted is r = 0.005, P=0.663. since p value > 0.05 level of significance, the correlation is not significant. R square value is 0.000025.     0.0025% of variance in government reduce income differences is explained by Blacks shouldn’t push where they are not wanted.

Correlation between government reduce income differences and political viewpoint is r = 0.240, P=0.000. since p value < 0.05 level of significance, the correlation is significant. R square value is 0.0576.   5.76% of variance in government reduce income differences is explained by political viewpoint.

The variable political viewpoint is useful in predicting attitudes about government involvement in reducing inequality.
