Step-by-Step Solution:
Step 1 of 3

Correlation Positive correlation – both variables increase or decrease together Negative correlation – two variables change in opposite direction No correlation – no linear relationship Nonlinear relationship – two variables are related but results in a scatter diagram that does not follow straight line Correlation coefficient (r) is a measure of the strength, its value is only -1 to 1 If no correlation, points won’t follow a straight line pattern, value of r is close to 0 If positive correlation, correlation coefficient is (0 < r = 1)  Perfect positive correlation r = 1 **value r close to 1 in a strong positive correlation and value r close to 0 is weak positive correlation
