A Pearson correlation coefficient close to +1 or -1 indicates that the two variables are highly correlated (positively or negatively, respectively). A correlation coefficient between 0 and +0.35 or between 0 and -0.35 was considered of having no correlation between the two variables. Statistics: Pearson coefficient was calculated using the SAS program.
