The issue with count variables is that they bounded at zero. This wreaks havoc on the assumptions of a linear model, which require continuous data. If none of your data are near zero, it would be less of an issue. Treating that count variable as continuous would give you predicted values that are non-integers, but perhaps that's not a big ...Study with Quizlet and memorize flashcards containing terms like A teacher has two large containers (A and B) filled with blue, red, and green beads, and claims the proportion of red beads is the same in each container.
