A researcher wants to examine the effect of room temperature on task performance. She places one group of participants in a room that is 54 degrees, a second group in a room that is 72 degrees, and a third in a room that is 90 degrees. She then measures the amount of time it takes each group to complete an identical task. This design would best represent a(n) design.

Independent group

Explanation: Experimental research involving more than one group or condition with separate participants or subjects attached to each condition is called an independent group design. Different participants are attached to each independent variable prednisone in the experiment.

In the scenario above, different participants were attached to each of the three independent groups(54 degrees, 72 degrees and 90 degrees) in other to examine the effect of room temperature on job performance. A usual downside of these experimental design is that individual ability or differences of the participants could affect our outcome, hence, leading to drawing up wrong conclusion
