ABSTRACT
A hypothesis test consists of a test between two competing hypotheses: a null hypothesis versus an alternative hypothesis. A common task in statistics is the process of “standardizing a variable.” By standardizing different variables, we make them more comparable. Conduct the same analysis comparing action movies versus romantic movies using the median rating instead of the mean rating. The variable id acts as an identification variable for all 48 rows, the decision variable indicates whether the applicant was selected for promotion or not, while the gender variable indicates the gender of the name used on the resume. First, try to imagine a hypothetical universe where no gender discrimination in promotions existed. In such a hypothetical universe, the gender of an applicant would have no bearing on their chances of promotion.
