8. Answer the following questions using the data for Shape C.
1. What is the median estimate for Shape C?
2. What is the difference between the largest estimate and the median estimate?
3. What is the difference between the smallest estimate and the median estimate?
4. Where do the estimates cluster?
5. The number line below shows the estimates for Shape C. Are there estimates that are not close enough to be useful? If so, which ones?

9. Below is the data table for Shape D. Answer the following questions using this set of data.
1. What is the median estimate?
2. Look at the data. Compare the estimates. Do any of the estimates seem unreasonable? Would you consider throwing out any of the data? If so, which one or ones?
3. Take out any pieces of data that seem “way off.” Now, find the median of the remaining data. Do highest and lowest estimates affect the median very much? Explain.
