I will conduct a survey using verified tools to determine whether a person expresses morningness or eveningness. In simple terms, one who expresses morningness tends to work better in the morning, and one who expresses eveningness tends to work better in the evening. I will use this in conjunction with another tool to determine whether a person is an introvert or extrovert. These two sets of data will help me find correlations between M/E and introversion/extroversion.
