The scatter plot is the basic tool for investigating the relationship between 2 quantitative variables. Check for a linear trend – never do a linear regression without first looking at the scatter plot If the assumptions (straightness of line) appear to be satisfied then fit a linear regression. The data suggests a linear trend.
