Pearson Product-Moment Correlation - When you should run this test, the range of values the coefficient can take and how to measure strength of association.

What does this test do?
The Pearson product-moment correlation coefficient (or Pearson correlation coefficient, for short) is a measure of the strength of a linear association between two variables and is denoted by r. Basically, a Pearson product-moment correlation attempts to draw a line of best fit through the data of two variables, and the Pearson correlation coefficient, r, indicates how far away all these data points are to this line of best fit (i.e., how well the data points fit this new model/line of best fit).
Citazione:
Are there guidelines to interpreting Pearson's correlation coefficient?
Yes, the following guidelines have been proposed:

Coefficient, r
Strength of Association Positive Negative
Small .1 to .3 -0.1 to -0.3
Medium .3 to .5 -0.3 to -0.5
Large .5 to 1.0 -0.5 to -1.0

Remember that these values are guidelines and whether an association is strong or not will also depend on what you are measuring.
