The conclusion that you will be able to reach if method I is used that cannot be concluded if method II is used is that the results can be generalized to the population as a whole.
In method I, the researchers decided to recruit volunteers. This sample includes people who do not exercise, people who exercise alone and people who exercise with a partner. On the other hand, method II will recruit participants at a community fitness center. Therefore, this sample will not include people who do not exercise.

The researcher who deals with scientific research that uses human beings must meet the ethical guidelines that guarantee the safety of the participating humans. There are several guidelines that must be applied according to the tests and the elements to which these human beings will be submitted.

In addition, the researcher must ensure that the research has a balance between risks and benefits and inform the participant of all of this. The researcher must ensure that the participant receives humane and fair treatment.
