In order to analyse the responses to a workplace mental health questionnaire, each employee's answers were used to calculate a well-being score. The maximum score on the questionnaire was 30, where a score of 0 represented extremely low well-being and a score of 30 represented extremely high well-being.
The following data was collected by the researcher.
Table 2: The number of overtime hours worked per week by each employee (labelled A – K) and their corresponding well-being scores.
| A | B | C | D | E | F | G | H | I | J | K | |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Number of overtime hours | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| Well-being score | 8 | 9 | 11 | 12 | 15 | 16 | 18 | 20 | 22 | 28 | 28 |
Explain why the median would be more suitable than the mode to represent the average well-being score for these employees.
