ANCOVA stands for Analysis of covariance, a statistics abbreviation.
ANOVA extended with one or more continuous covariates, comparing group means after adjusting for variables such as baseline scores or age. It is common in clinical trials and educational research.
Example: An ANCOVA adjusting for pretest scores showed higher posttest scores in the tutoring group.
Usage notes
Adjusting for a baseline measure usually increases statistical power. ANCOVA assumes the covariate relates to the outcome in the same way in every group, known as homogeneity of regression slopes. Regulatory guidance for randomized trials generally accepts ANCOVA with baseline adjustment as a primary analysis.
