Higher June 2024 Paper 1 Q16
16 The table shows information about the ages of members of two clubs.
| Median age (years) | Interquartile range of ages (years) | |
|---|---|---|
| Swimming club | 21.2 | 7.3 |
| Cycling club | 29.7 | 4.6 |
Compare the average age and consistency of ages for the members of the two clubs. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| A correct comparison of the average age of the two clubs | B1 | eg the average (age) of the cyclists was higher/older the median (age) of the swimming club was lower/younger, (so the average was lower/younger) |
| A correct comparison of the consistency of the ages of the two clubs | B1 | eg the cycling club has more consistent ages the interquartile range of the swimming club was higher, so they were less consistent in age |
Additional guidance
| Statements must be comparisons eg1 (the average age at) the cycling club was higher eg2 (the average age at) the cycling club was high | B1 B0 |
| Statements reversed | B0 |
| Do not allow incorrect values supporting statements | |
| Ignore non-contradictory statements with correct statements | |
| Average age statements | |
| The swimming club are (8.5 years) younger (on average) | B1 |
| Cycling club members are (8.5 years) older (on average) | B1 |
| Younger people prefer swimming (to cycling) | B1 |
| Young people prefer swimming (to cycling) | B0 |
| Average age has 8.5 years difference | B0 |
| The cycling club has more older people | B0 |
| Consistency statements | |
| The cycling club is more consistent / has better consistency | B1 |
| There is a smaller (interquartile) range for cycling, so it’s more consistent | B1 |
| Ages of the cycling club are closer together | B1 |
| Consistency at the cycling club is bigger | B1 |
| Consistency at the cycling club is smaller | B0 |
| More people are in the same age group in the cycling club | B0 |
| The difference in interquartile range is 2.7 | B0 |
| The swimming club had a higher (interquartile) range | B0 |
| The swimming club had a higher range of ages | B0 |
| More of an age gap / age range in the swimming club than the cycling club | B0 |
