Some business analysts prefer to use parametric tests over non-parametric tests because they are more powerful in detecting differences between groups. Non-parametric tests may require larger sample sizes or be less sensitive to detecting small differences. However, if the normality assumption has been violated, the results of parametric tests may not be accurate or reliable. Therefore, the primary reason is that they perceive non-parametric tests as less powerful, not because they are harder to carry out, less robust, or more likely to show causal effects.
