A simple introduction to help you understand correlations and correlational studies. Includes examples and important considerations

A positive correlation result means that both metrics increase in relation to each other, while a negative correlation means that as one metric increases,...
The correlation coefficient is always between -1 and +1. The closer the correlation is to +/-1, the closer to a perfect linear relationship. Here is how I tend to interpret correlations. -1.0 to -0.7 strong negative association.
