What percentage difference is enough of a difference
to indicate that two categorical variables would be
independent.
Give your reason.
Homework Answers
If the difference in proportions of two different categorical random variables is zero or nearly close to zero we say that the two categorical variables are independent. If we calculat relative risk then the two categorical variables will be independent if and only if the ratio equals one.
