One measure of this is Kendall's tau, and one form of this can be used to estimate the periodicity of a signal. A rank-order version coefficient for this is named for Spearman, though a statistic introduced by Francis Galton, Pearson's r coefficient, is the most widely used.

A rank-order version coefficient for this is named for Spearman, though a statistic introduced by Francis Galton, Pearson's r coefficient, is the most widely used. When r equals negative one, this is said to be completely negative; this is completely positive when r equals one. For 10 points, name this measure of association between two variables, which often implies but does not equal causation.
