Examining Correlations

In this chapter you examine relationships between pairs of variables by looking at correlations.

You can use correlation coefficients to measure the strength of the linear association between two variables. You can also use confidence ellipses in scatter plots as a visual test for bivariate normality and an indication of the strength of the correlation.
