The Analysis of Covariance (generally known as ANCOVA) is a statistical methodology for incorporating quantitatively measured independent observed (not controlled) variables in a designed experiment. Such a quantitatively measured independent observed variable is generally referred to as a covariate

MANCOVA Covariates MANCOVA and MANOVA Discussion
Use an ANCOVA, with pressure as the covariate, to test whether there is a significant difference in the numbers of fibres transferred between the different pairs of fabrics. Video answer: Use of Minitab to perform Analysis of Covariance (ANCOVA) NOTE: In good experimental design, it would be important to choose the values of the relevant factors (e.g. pressure) to produce a balanced design and how to build a lego car in solidworks Introduction The ANCOVA (analysis of covariance) can be thought of as an extension of the one-way ANOVA to incorporate a "covariate". Like the one-way ANOVA, the ANCOVA is used to determine whether there are any significant differences between the means of two or more independent (unrelated) groups (specifically, the adjusted means)..
