Directions: Using the integers 0-9 (without repeating any number), create a set of points that have the following characteristics:
Non-linear Positive Correlation
(__,__) (__,__) (__,__) (__,__) (__,__)
Non-linear Negative Correlation
(__,__) (__,__) (__,__) (__,__) (__,__)
No Correlation
(__,__) (__,__) (__,__) (__,__) (__,__)
Hint
What does it mean to have correlation? What are the characteristics of those correlations?
Answer
There are many possible solution combinations. Here is an example of each.
Non-linear Positive Correlation: (0,4) (1,6) (2,8) (3,7) (5,9)
Non-linear Negative Correlation: (0,9) (1,7) (2,8) (3,5) (6,4)
No Correlation: (0,5) (1,2) (3,9) (4,8) (7,6)
Non-linear Positive Correlation: (0,4) (1,6) (2,8) (3,7) (5,9)
Non-linear Negative Correlation: (0,9) (1,7) (2,8) (3,5) (6,4)
No Correlation: (0,5) (1,2) (3,9) (4,8) (7,6)
