Do taller players score more runs, and do prices and demand move in opposite directions.

It explains positive, negative and zero correlation, scatter diagrams, Karl Pearson coefficient and rank correlation with simple merits and limits. You will learn to read scatter patterns, calculate coefficients for small data sets and to avoid mistaking correlation for cause and effect.
