Scatter Plot: Strong Linear (positive correlation) Relationship

Scatter Plot Showing Strong Positive Linear Correlation scatter plot showing strong positive linear correlation
Discussion Note in the plot above how a straight line comfortably fits through the data; hence a linear relationship exists. The scatter about the line is quite small, so there is a strong linear relationship. The slope of the line is positive (small values of X correspond to small values of Y; large values of X correspond to large values of Y), so there is a positive co-relation (that is, a positive correlation) between X and Y.
