An advanced analysis of variance procedure in which the effects of one or more metric-scaled extraneous variables are removed from the dependent variable before conducting the ANOVA is called ________.
A) analysis of covariance (ANCOVA)
B) one-way analysis of variance
C) decomposition of the total variation
D) n-way analysis of variance

ANCOVA (analysis of covariance) is the procedure in which the effects of one or more metric-scaled extraneous variables, also known as covariates, are removed from the dependent variable before conducting ANOVA (analysis of variance). This allows a more precise examination of the effects of the independent variable on the dependent variable by controlling for the effects of the covariate. The other options (B, C, and D) do not involve the removal of extraneous variables from the dependent variable.
