Analysis of covariance (ANCOVA) is a statistical technique that combines elements of both analysis of variance (ANOVA) and regression analysis. This method is particularly valuable in the realm of research methodology for management decisions, as it allows researchers to examine the impact of categorical independent variables on a continuous dependent variable while controlling for the influence of one or more continuous variables, known as covariates.

The statement "Analysis of covariance is a combination of the two techniques – analysis of variance and regression" reflects the fundamental nature of ANCOVA and its bridging role between ANOVA and regression analysis.
