Foundation June 2019 Paper 1 Q18
18 Here is some data about the people listening to a radio station one day.
| Percentage | Mean number of hours listening | Range of number of hours listening | |
|---|---|---|---|
| Aged 40 or under | 21 | 1.2 | 4.5 |
| Aged 41 or over | 79 | 6.3 | 13.9 |
Compare the data for people aged 40 or under with the data for people aged 41 or over.
Make three comparisons. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Valid statement about proportion | B1 | eg there were more 41s or over than 40s or under |
| Valid statement about average | B1 | eg the average listening time of the 41s or over was higher |
| Valid statement about spread | B1 | eg the listening times of the 41s or over were more spread out |
Additional guidance
| Do not allow incorrect values supporting statements (eg a miscalculation) but repeating the values in context is acceptable | |
| Condone irrelevant statements with correct statements | |
| Student statements may not be in the same order as the measures in the table | |
| Accept ‘older people’ for 41s or over and ‘younger people’ for 40s or under similarly accept over 40s to stand for 41s and over (oe) | |
| Proportion of the audience statements | |
| There were more over 41s | B1 |
| They are mostly over 41 | B1 |
| There were 58% more over 41s than 40s and under | B1 |
| The proportion / % / percentage of over 41s is higher | B1 |
| Over 41s are a higher proportion than 40s and under | B1 |
| Less 40 and under than over 41 | B1 |
| The 40 and unders were 21%, the over 41 were 79% | B1 |
| The 40s and under were 21% which is less than half/quarter | B1 |
| The 40s and under were 21% | B0 |
| The difference is 58% | B0 |
| Average listening time statements | |
| The over 41s had a higher mean | B1 |
| Over 41s listened for 5.1h more (on average) | B1 |
| Over 41s listened longer (on average) than the 40s and under | B1 |
| 41+ longer listening (on average) | B1 |
| (More/most) 40s and under listened less than the over 41s (on average) | B1 |
| Average listening 5.1 hours difference | B0 |
| Spread of listening time statements | |
| The over 41s had a higher range | B1 |
| More of a time gap in the over 41s than the 40s and under | B1 |
| Over 41s have a higher spread | B1 |
| 40s and under times are closer together than over 41s | B1 |
| Over 41s have a wider listening time range | B1 |
| The 41 and over listening time gap was high, the under 40 listening time gap was low | B1 |
| 40 and under is 4.5, 41 or over is 13.9 | B1 |
| 40 and under listen to the radio 4.5 hours, 41 or over listen to the radio 13.9 hours | B0 |
| The difference in range is 9.4 | B0 |
| Listening times were quite close together | B0 |
| The 41 and over listening times gap was high | B0 |
