Aresearcher divides participants into those who suffer from insomnia and those who sleep well. he compares the two groups on the number of hours each spends at leisure activities in an average week. he finds the insomniacs spend significantly fewer hours at such activities than do the participants who sleep well. in this example, the number of hours spent at leisure activities is:
1. the independent variable.
2. the dependent variable.
3. confounded with which group the participant is in.
4. the hypothesis.

2. The dependent variable.

Explanation:

According to my research on the scientific method, I can say that based on the information provided within the question the number of hours spent at leisure activities is the dependent variable. This can be said because in this situation whether or not a person is an insomniac seems to depend on the number of hours that they spend on leisure activities. Therefore it can be classified as the dependent variable in this experiment.
