Scatter Plots 1

Directions: Using the integers -9 to 9 at most one time each, fill in the boxes to create two sets of six points: one that has a positive association and one that has a negative association. You may reuse all the integers for each equation.


How should you create points such that they have any association? How can you tell whether the association is positive or negative?


There are many possible answers, but in general they should form something resembling a line that slopes up to the right for a positive association and down to the right for a negative association. One example of a positive association is (-9, -8), (-7, -6), (-5, -4), (-3, -2), (-1, 0), (1, 2) and one example of a negative association is (-9, 8), (-8, 6), (-7, 4), (-6, 1), (-5, 0), (-4, -3).
