ANCOVA
ANCOVA
is a procedure like ANOVA except researchers can study the effects of one or
more independent variables on a dependent variable after adjusting for other
variables, called covariates, which
were not a primary focus of the study. The letter C in ANCOVA stands for covariate.
There can be several covariates in a study. In testing for differences among
groups experiencing different leadership styles, we could study the effects on employee
satisfaction after adjusting for a covariate of years of employment. A key word
in ANCOVA studies is adjusting.
Analysts adjust the scores based on information about the covariate before
testing for significant differences.
Basic features of an ANCOVA:
Independent Variable = 1 or more
Dependent Variable = 1
Covariate = 1 or more
