The coefficient of correlation measures the strength and direction of a relationship between two variables, ranging from -1 to +1. A positive correlation means that both variables move in the same direction, while a negative correlation means that they move in opposite directions. A correlation of 0 indicates no relationship between the variables. The coefficient of correlation does not indicate causation or whether or not the principle of falsifiability applies to each variable. It also does not address unintended changes in a subject's behaviour.
