## The Power of Power Analysis

How can power analysis help us in designing our method? Isn’t significance enough? Not really.

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.

Relative Risk utilizes the probability of an event occurring in one group compared to the

## MLQ Leadership Styles

At the end of the survey, three MLQ leadership styles are created: transformational, transactional, and passive avoidant leadership. Often times, researchers wish to classify their MLQ participants into being one leadership type. However, this isn’t realistically possible due to how the
