Jules conducted a survey and asked 100 people how many years of education they have and what their annual income is. She used the results to make a scatter plot. What type of association should he expect to see in the scatter plot?

• Positive Association

• Negative Association

• No Association

Which best describes the association shown in the scatter plot?

• Negative and linear

• Negative and non-linear

• Positive and linear

• Positive and non-linear

• The number of miles driven and the gallons of gas used.

• The number of students in a school and the number of unused lockers.

• The number of items ordered at a restaurant and the cost of the bill.

• The number of customers in a store and the length of the wait at the register.

• Scatter Plot B because the points are further apart.

• positive

• negative

• none

If a scatterplot has no correlation then...

• ...it has no ordered pairs

• ...it has ordered pairs that have a negative pattern

• ...its ordered pairs have no predictable pattern

• ...if it makes a lion on a graph (roar!)
