    Most of them can be either, depending on how you measure them. For example: Height would be qualitative if it were Tall, Medium, Short and quantitative if the actual height in numbers (120 cm). The same is true for Age. It would be qualitative if grouped into Old vs. Young, but quantitative if the actual age in years (33 years old).

    Race, Gender, and Color are always qualitative categories. Direction (N, S, E, W) might seem like it too would always be qualitative, but if you measured the actual degrees it would be quantitative.
