we would interpret this "non-significant" correlation to mean there is no linear relationship between the variables -- that's what H0: testing means (a couple acknowledged the non-significance and then interpreted the correlation, based on the idea the effect size wasn't trivial -- that's OK, but may get punished in research reports!

If one variable is thought of as the predictor and another variable as the criterion, we can square the correlation coefficient to interpret the strength of the relationship. The square of the correlation (r2) gives the proportion of criterion variance that is accounted for by its linear relationship with the predictor.
