A researcher investigated college students' self-reported helpfulness in common areas. The college has 4 main departments, with 200 students per department.
He conducted face-to-face interviews individually with 10 students. One of the questions in the interview was, 'How many times have you assisted in cleaning or tidying the college common room this term?' The results from this question are shown in Table 1.
