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.

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.

GPT-4o mini · Answer

The response variable in this experimental study is the average happiness ratings of the participants. This is measured on a scale of 1 to 10 at the end of each exercise session, and the researchers use these ratings to compare the happiness levels between the two groups (those exercising outside and those exercising inside).
