Ways to measure statistical relationships include: A scatter plot.
What is the difference between correlation and association of attributes?

(Although the terms correlation and association are often used interchangeably, correlation in a stricter sense refers to linear correlation, and association refers to any relationship between variables.)
How to determine the association between two variables?
Chapter 4. Association between Two or More Variables Very frequently social scientists want to determine the strength of the association of two or more variables. For example, one might want to know if greater population size is associated with higher crime rates or whether there are any differences between numbers employed by sex and race.
Which is an example of a statistical relationship?
