Question

Researchers want to investigate whether people feel happier after exercising outside or exercising inside. Four hundred adults who already exercise regularly are randomly chosen to participate in the study. They are divided randomly into two groups. One group is asked to exercise inside at least five times a week, while the other group is asked to exercise outside at least five times a week. All participants are asked to rate their happiness on a scale of 1 to 10 at the end of each exercise session. At the end of the study, researchers compare the average happiness ratings of the outside exercise group to the average happiness ratings of the inside exercise group.
What are the treatments in this experimental study?

Answer 1

In this experimental study, the treatments are the two different exercise environments that the participants are grouped into:

1. **Exercise Inside**: This treatment involves participants who are asked to exercise indoors at least five times a week.

2. **Exercise Outside**: This treatment involves participants who are asked to exercise outdoors at least five times a week.

The researchers will compare the average happiness ratings of the participants in these two groups to determine the effect of the exercise environment on happiness.
