Analysis of Covariance (ANCOVA) in the Context of Research Methodology for Management Decisions

Analysis of Covariance (ANCOVA) is a statistical technique that combines elements of both analysis of variance (ANOVA) and regression analysis. This integration allows researchers to assess the impact of an independent variable on a dependent variable while statistically controlling for the influence of one or more covariates.
