We tested 22 variables for correlation and made a correction to the p value for multiple comparisons to avoid a false discovery rate, since, statistically, with an alpha value of 0.05, 1 out of 20 correlations would be a false positive. We used a Bonferroni correction by dividing the alpha by .05/22, resulting in a significant p value of 0.002.
