Erik observes that when he dresses in business casual, people seem more comfortable approaching him. He wants to know if this is true because it is very important to him that he meet new people at college. If Erik uses the scientific method to investigate this, what type of research would he be doing?

The best answer to the question: If Erik uses the scientific method to investigate this, what type of research would he be doing, would be, observational as full participant.

Explanation:

In observational research methods, a person simply tries to answer a question, or solve an issue, by literally observing and experimenting on the field, without making changes to what is around. The question, or issue, will be resolved as the researcher observes the development of certain characteristics that would prove, or disprove, the question being researched, or solve, or not solve, the problem for which an answer is being sought. In this case, Erik wishes to see if his previous experiences dressing in business casual attire will repeat themselves when he is in college, and so, he not only wishes to test the theory that people approaches him easily if he is dressed in business casual, rather than in another attire, but he will become the test subject himself, becoming thus, a full participant. Erik will then observe the results of his experimentation, and thus come to an answer to his query.
