Find the mode and median respectively of the distribution below.
| No. of children | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|---|
| No. of families | 7 | 11 | 6 | 7 | 7 | 5 | 3 |
Worked solution (try it first)
- The mode is the number of children with the most families: 1 child, 11 families.
- There are families, so the median is halfway between the 23rd and 24th.
- Running totals: 7, 18, 24.
- The 19th to 24th families all have 2 children, so the median is 2.
- So the mode and median are 1 and 2, option B.
