Question

Which kind of a design is an RCT using a factorial design?

a. Experimental and analytic

b. Experimental and descriptive

c. Observational and analytic

d. Observational and descriptive

Answer 1

From the given information,

We know that,

“A study design that randomly assigns participants into an experimental group or a control group. As the study is conducted, the only expected difference between the control and experimental groups in a randomized controlled trial (RCT) is the outcome variable being studied. also An alternative may be a factorial trial, where for two interventions participants are allocated to receive neither intervention, one or the other, or both. Factorial trials require special considerations, however, particularly at the design and analysis stages.

Hence,

Experimental and analytic is the correct answer.

Thank you.
