AQA Product moment correlation coefficient ranges
I think that there are ranges of the correlation coefficient used by AQA to determine the qualitative strength of correlation but I don't have a copy of the ranges. I'm talking about like 0.95< |r| <0.99 is 'very strong'.
Does anyone know or have them?

0.9 < r < 0.99 indicates (very) strong/almost exact positive correlation
0.7 < r < 0.9 indicates strong positive correlation
0.3 < r < 0.7 indicates moderate/some positive correlation
0.1 < r < 0.3 indicates (very) weak/almost no (positive) correlation
0.0 < r < 0.1 indicates no (positive) correlation
Similar guidelines apply for negative values.
