4.) You want to look at the relationship between gender and wages. However, you notice that gender is a categorical variable and wage is a numerical variable. One way to work on two different types of variables is to transform one variable to the type of the other. You decide to generate a categorical variable based on the level of wage, and this categorical variable has two values, "high" and "low". For example, you choose a threshold value for wage, and if a respondent's wage is no less than the threshold value, you enter "high" and enter "low" otherwise. i. Describe in detail how you have decided the threshold value for generating the new categorical variable for the level of wage. Then use an appropriate graph to present this variable. (Hint: you may choose to use an appropriate numerical measure of wage as the threshold value). ii. Present these two categorical variables together using an appropriate graph, and then discuss what the graph shows
