Z . Examine the variables graphically. For two interesting categorical variables, construct a b. distribution of the variable. Comment on each. Examine the distribution of all numeric variables, using histograms. (Need not include in report.) Make a little table listing (in alphabetic order) the variables which are not normally distributed, along with the transformation function needed to induce normality {e.g. log}. For each variable, perform the transformation to induce approximate normality. all such variables. fore f a: Provide be: Eter histograms for
