WebAccording to Cohen (1992), for a correlation coefficient of the same magnitude as the one reported in Sim et al. (2015), a sample size of 85 would be required in order to draw conclusive inferences regarding the correlation test. This is the case even if the magnitude of the correlation coefficient is the same.
