What is the physical interpretation of correlation?

In very basic and physical sense, a positive correlation means that higher values of one variable are associated with higher values of the other variable. A negative correlation means that bigger values of one variable tend to co-occur with smaller values of the other variable.

How do you interpret Pearson correlation results?

Pearson Correlation – These numbers measure the strength and direction of the linear relationship between the two variables. The correlation coefficient can range from -1 to +1, with -1 indicating a perfect negative correlation, +1 indicating a perfect positive correlation, and 0 indicating no correlation at all.

Is 0.4 a strong correlation?

For this kind of data, we generally consider correlations above 0.4 to be relatively strong; correlations between 0.2 and 0.4 are moderate, and those below 0.2 are considered weak.
