What does ANACOVA stand for?

Analysis of covariance (ANCOVA) was used to compare treatment groups by race by PTSD scores.

Subsequent chapters address completely randomized design, multiple comparison tests, trend analysis, among other topics, ending with chapters on split-plot factorial design, analysis of covariance, Latin square and related designs, confounded factorial designs, and fractional factorial designs.

Changes in breast density were assessed using an analysis of covariance (ANCOVA) model.

We computed analysis of covariance (fellowship being a categorical independent variable) with non-musculoskeletal sports medicine items as the dependent variable.

We also found significant differences between the four racial/ethnic groups on the MRNI-R Total Scale, through univariate analysis of covariance by race/ethnicity on the MRNI-R Total Scale.

Results of multivariate analysis of covariance (MANCOVA) controlling for custody status, counselling status and history, and psychiatric history showed that young black males citing a high frequency of negative social contextual experiences reported significantly greater cultural mistrust of mental health professionals and significantly less positive attitudes toward seeking professional help for mental health problems than young black males reporting a low frequency of negative social contextual experiences.

With the use of an analysis of covariance, with pretest scores used as the covariate, the achievement improvements were statistically significant.
