The greater the absolute value of a correlation coefficient, the stronger the linear relationship. The weakest linear relationship is indicated by a correlation coefficient equal to 0. - the answers to answer-helper.com A. This means that when one variable increases by one, the other variable also increases by the same amount. A correlation measures the relationship between two variables, that is, how they are linked to each other. When two things are highly correlated, one causes the other. 1.

What is the difference between a positive correlation and a negative correlation? a. In statistics, we call the correlation coefficient r, and it measures the strength and direction of a linear relationship between two variables on a scatterplot. Which of the following values of r represents the strongest correlation between two variables that exhibit a linear association? Answer: -0.85 (Option d) is the strongest correlation coefficient which represents the strongest correlation as compared to others.
