Unit 3 Assignment 2: Linear Relationships
Number 1
The correlation coefficient is 0.663. A moderately strong positive linear relationship exists
between longevity and gestation. A unit increase in gestation period increases the longevity
period. Removing outlier decreases the correlation coefficient.
Question 2
The new correlation coefficient is 0.519.

The new correlation coefficient is less than the correlation coefficient in question 1. The outlier
was influential point far from the estimated regression model on the upper side. Therefore,
inclusion of the outlier point increases correlation coefficient value.
