Question 1:
Report the correlation between gestation and longevity and comment on the strength and direction of the relationship-
Interpret your findings in context-
Now return to the scatter plot that you created earlier. Notice that there is an outlier in both longevity (40 years) and
gestation (645 days)- Note: This outlier corresponds to the longevity and gestation period of the elephant-
What do you think will happen to the correlation if we remove this outlier?
Question 2:
Report the new value for the correlation between gestation and longevity and compare it to the value you found earlier
when the outlier was included- What is it about this outlier that results in the fact that its inclusion in the data causes the
correlation to increase?
