The relationship is linear because both the diameter and the unit vary constantly, except for Scott.

RESULTS PART 2

Bounty Brawny Viva Scott Basic Thirsty

The relationship of the two lines are not linear because the unit prices are very similar for all brands.

Advice for Shoppers!

Scott is the best value

brand because it has the

lowest unit price of one

cent. Also, it is tied for the

second highest diameter and

area of absorbency.
