The Power of Power Analysis

How can power analysis help us in designing our method?  Isn’t significance enough?  Not really.  Significance only tells us how unlikely a Type II error would be, given our method—we may still have a potential Type I error.  As well, something can be significant, and not be important.  Cohen (1992) has long argued that significance

Pearson’s Correlation Coefficient, The Most Commonly Used Bivariate Correlation

It is difficult to understate the value of the correlation coefficient to descriptive statistics.  Use of the term “correlation coefficient” is almost always a short-hand phrase for the Pearson product-moment correlation coefficient.  There are several other well known correlation coefficients such as Spearman’s rho rank correlation coefficient but it usually a safe assumption the correlation

At the end of the survey, three MLQ leadership styles are created: transformational, transactional, and passive avoidant leadership.
