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)n-way analysis of variance
D)decomposition of the total variation

Quizplus · Accepted Answer

Analysis of covariance (ANCOVA) is the correct answer as it is an advanced analysis of variance procedure that controls for the effects of one or more extraneous variables (also called covariates) that are measured on a metric scale by incorporating them into the analysis as predictors. This allows for a more accurate assessment of the effect of the independent variable on the dependent variable, which is the primary purpose of ANOVA. The other options (B, C, and D) are not the correct answer as they do not specifically incorporate the control of extraneous variables, which is a key feature of ANCOVA.
