ANCOVA stands for which of the following?

Explanation:
ANCOVA stands for Analysis of Covariance. It blends ideas from ANOVA and regression: you compare group means like in ANOVA, but you also include one or more continuous covariates in the model to remove variance those covariates explain. This means the group means are adjusted as if all groups had the same covariate value, allowing a fairer comparison of the group effects after accounting for the covariate’s influence. In practice you fit a general linear model with a categorical factor (the groups) and one or more numeric covariates, and you test whether the adjusted means differ across groups. The other options point to different concepts or methods that don’t involve adjusting means by covariates.
