No, the two variables have to be measured on either an interval or ratio scale. However, both variables do not need to be measured on the same scale (e.g., one variable can be ratio and one can be interval). Further information about types of variable can be found in our Types of Variable guide. If you have … See more Yes, the following guidelines have been proposed: Remember that these values are guidelines and whether an association is strong or not will also depend on what you are measuring. See more No, the two variables can be measured in entirely different units. For example, you could correlate a person's age with their blood sugar levels. Here, the units are completely different; age is measured in years and blood sugar … See more It is important to realize that the Pearson correlation coefficient, r, does not represent the slope of the line of best fit. Therefore, if you get a Pearson correlation coefficient of +1 this … See more The Pearson product-moment correlation does not take into consideration whether a variable has been classified as a dependent or independent variable.
