Which of the following describes a mixed-model design?
A) One between-groups factor and one repeated-measures factor

D) One independent variable is normally distributed and another one is not

Question

Quizplus · Accepted Answer

A mixed-model design refers to a design that includes both between-groups factors and repeated-measures factors. In this case, there is one between-groups factor (e.g. a categorical variable such as gender or treatment) and one repeated-measures factor (e.g. a continuous variable measured over time such as blood pressure or reaction time). Option A describes a design that includes one between-groups factor and one repeated-measures factor, making it the best choice for a mixed-model design. Option B describes a design with only between-groups factors, while option C describes a design with independent variables measured on different scales, and option D describes a distributional issue rather than a design feature.
