Remember the correlation coefficient or the r-value tells you how well the variables are related, the closer the r-value is to +1 or -1, the stronger the correlation between the variables. Generally, r ≥ 0.7 is considered strong, r ≤ 0.5 is considered weak, if r = 0 there is no relationship between the variables
