1.  What is a scatterplot?  What types of trends (correlation) does a scatterplot show?  A graph that can show trends of information. Made with ordered pairs scattered on a coordinate plane.  Positive, Negative, No correlation, undefined correlation

2.  Positive: Moving from left to right on the graph, the points move upward. As your domain increases, your range also increases.  Examples: The longer you drive, the more miles you put on your car.  The more you talk on your cell phone, the higher your bill.

3.  Negative: Moving from left to right, the points move downward. As the domain increases, the range decreases.  Examples: The longer the candle burns, the shorter the height.  The older a car is, the less it is in value.

4.  No correlation: There is no pattern on the graph. No line of best fit.  Examples: Your grade in class and how many people are in your family.  The temperature outside and how much you spend on groceries.

5.  Undefined Correlation: A vertical or horizontal line on the graph.  Examples: Shoes size and age.  Age of kids in a 1 st grade class and their height.
