Analysis

Part 1: Describe your Data

Discuss the following features of the scatter graph:

1. Trend
   Does the relationship look linear?
   Do most points in the graph lie in straight band?

2. Direction
   How does the Response variable respond to changes in the Explanatory variable?
   When the Explanatory variable increases, what happens to the Response variable. Does it increase or decrease?

3. Strength
   How strong does the relationship look?
   Is the straight band that covers most of these points wide or narrow? i.e Are the points close to middle line or are they scattered far from it?

4. Groupings
   Are there any obvious clusters of points ? 

5. Unusual Values
   Are there any values that are unusually far from the other points?
