Question

Quizplus · Accepted Answer

The independent variables in this experiment are different amounts of a drug, which can be measured quantitatively (e.g. 10mg, 20mg, 30mg). They are not abstract, as they can be physically measured, nor are they qualitative, as they are not subjective or categorical in nature. It is not a factorial design as there is only one independent variable (amount of drug), not multiple factors being manipulated.
