1939 C. H. Goulden Methods Statist. Anal. xv. 247 For a single variable the variation is frequently heterogeneous and may be sorted out into components... The same is true for the correlated variability or covariation of two variables, and the mechanism for sorting out the covariance effects is known as the analysis of covariance.
