Suppose you are interested in genealogy and want to try to predict your potential longevity by using the ages at death of your ancestors.
You find out the ages at death for the eight great-grandparents of you mother and father.
Suppose the ages in numerical order are:
Mother?s Great Grandparents: 78, 80, 80, 81, 81, 82, 82, 84
Father?s Great Grandparents: 30, 50, 77, 80, 82, 90, 95, 98
1. Compare the medians for the two sets of data. How do they compare?
2. Compare the means for the two sets of data. How do they compare?
3. Which set do you think is more useful for predicting longevity in your family? Explain why.
