JAMB 1988 · UME · Q49
In the distribution below, the mode and the median respectively are
| Score () | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|---|
| Frequency | 7 | 11 | 6 | 7 | 7 | 5 | 3 |
Worked solution (try it first)
- The mode is the score with the highest frequency: score 1, which occurs 11 times.
- There are scores, so the median is halfway between the 23rd and 24th.
- Running totals: 7 (score 0), 18 (score 1), 24 (score 2).
- The 19th to 24th scores are all 2, so the median is 2.
- So the mode and median are 1 and 2, option B.
