1. Scatterplots Thinking Skill: Explicitly assess information and draw conclusions

2. Scatterplot: A graph on the coordinate plane that shows relationships between two quantities Sc atterplots are helpful to see trends in data and make predicitons Sales What conclusion can you make from this scatter plot?

4. Ex 1: Draw a scatterplot and describe the relationship (if any) Monitor Size (inches) Price 17in $99 19in $149 32in $219 27in $189

5. Ex 2: Use a scatterplot to make predictions 1.) How many miles/gallon does a car that weighs 2800lbs get? 2.) How much does a car that gets 20mpg typically weigh? 3.) How many miles per gallon would a car that weighs 1 ton get? 4.) How much would a car that gets 25mpg weigh? 5.) Describe the relationship between weight of a car and gas mileage. Weight Miles per gallon
