- IntermediateFour numbers 4, 7, 13 and x have a median of 10; find x.
- IntermediateTwenty-one numbers are arranged in order; which position holds the median?
- IntermediateFive numbers average 12; after two more numbers are added the seven average 14; find the total of the two new numbers.
- ChallengeFor the data 1, 2, 3, 4 and 100, by how much does the mean exceed the median?
- ChallengeThe data 6, 6, 9 and 9 gain one more 6; find the new mode.
- ChallengeSix numbers 3, 6, 8, x, 15 and 18 have a median of 9.5; find x.
- Error redoError clinic: the data 2, 3, 3, 4, 8 and 9 have a mode of 3, and a student answered 3 as the median too. Find the correct median.
03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 23.5 | For ten values the fifth and sixth, 22 and 25, average to 23.5. |
| 2 | 17 | The total 105 minus 88 leaves 17. |
| 3 | 8 | There are seven values, so the fourth, 8, is the median. |
| 4 | 13 | The median averages the middle two, so 7 and x average to 10, giving x equal to 13. |
| 5 | 11th | For an odd count the median sits at position 21 plus 1 over 2, which is 11. |
| 6 | 38 | The old total is 60 and the new total 98, so the two new numbers add to 38. |
| 7 | 19 | The mean is 110 over 5, which is 22, while the median is 3, a difference of 19. |
| 8 | 6 | After the addition 6 appears three times while 9 appears twice. |
| 9 | 11 | The middle two are 8 and x, and 8 plus 11 is 19, which averages to 9.5. |
| 10 | 3.5 | The median averages the middle two values 3 and 4, giving 3.5. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Check the answers, and for any wrong item confirm the data were ordered before the median was taken.Tutor Registration →
