Reducing Bias and Error in the Correlation Coefficient Due to Nonnormality
Reducing Bias and Error in the Correlation Coefficient Due to Nonnormality
It is more common for educational and psychological data to be nonnormal than to be approximately normal. This tendency may lead to bias and error in point estimates of the Pearson correlation coefficient. In a series of Monte Carlo simulations, the Pearson correlation was examined under conditions of normal and …
