Quizplus · Accepted Answer

A Pearson correlation coefficient of .50 indicates a moderate positive correlation. This is best represented by an ellipse with a football shape, as the points on a scatterplot will be somewhat grouped together in a diagonal pattern. An absolute value of 1.00 indicates a perfect correlation, which could be represented by a straight line or a curve. A correlation of 0.00 indicates no correlation, which would be represented by a random scatter of points. A correlation of -1.00 indicates a perfect negative correlation, which could also be represented by an ellipse.
