Question

Oliver is determining the number of males in his math class. Oliver is collecting what kind of data? A) bivariate B) categorical C) qualitative D) univariate

Answer 1

When Oliver is considering the number of males, he typically assigns people to two categories: make or female, which makes the variable bi-variate : with two values.("bi" means "two).


If he's more inclusive, and adds the category of "other", it would be a categorical data - with 3 categories.
