Analysis of covariance (ANCOVA) is an analysis technique that is applied to two variables in order to determine the strength of relationship between the two variables. This determines how the variables change together. This data analysis technique employs a general linear model. This means that is combines the analysis of variance as well as regression analysis to one data set. One of the variables to be tested has to be an independent variable while the other variable needs to be a dependent variable. The analysis determines the variance of the means of the dependent variable as compared to the independent variable ...
