- D6, 20, 5, 15
- E6, 22, 14, 15

**Q7: **

Find the value of given that the mode of is 12.

**Q8: **

A group of students were selling boxes of cookies to raise money for a charity. The line plot shows how many boxes of cookies the students sold. Determine whether the mode would be a good measure of central tendency for the data or not, and explain why.

- ANo, the mode is not a good measure of central tendency because it is very high compared with the other data points.
- BYes, the mode closely represents the middle of the data.

**Q9: **

Emma cycles 20 miles every Monday, 13 miles every Wednesday, and 17 miles every Friday. Describe how the mode would be affected if Emma adds a 24-mile bike ride every Saturday.

- AThe mode would remain unchanged at 17.
- BThere would be a mode of 24 instead of no mode.
- CThe mode would increase from 13 to 24.
- DThe mode would decrease from 24 to 13.
- EThere is no mode either way.

**Q10: **

The table shows Jacobβs savings per day. Describe how the mode would be affected if the $14.90 savings were not included.

---|---|---|---|---|---|---|

Savings | $6.60 | $11.40 | $12.30 | $8.00 | $9.00 | $14.90 |

- AThere is no mode either way.
- BThe mode would remain unchanged.
- CThe mode would increase.
- DThe mode would decrease.
