Answer: D - Treatment conditions (A or B) are not continuous data.

Key Takeaway: Continuous data indicates that observations are numerical values and not limited to nominal categories (such as gender or employment status). For example, the temperature in a standard over would often range from zero degrees Celsius to over 500. The same can be said of other continuous measures such as money spent and gas mileage in a vehicle. A treatment condition comprised of two levels (A or B) is considered to be categorical data.
