aMultivariate analysis of covariance MANCOVA is a statisticaltechnique that is the extension of analysis of covariance ANCOVABasically it is the multivariate analysis of variance MANOVAwith a covariates In MANCOVA we assess for statisticaldifferences on multiple continuous dependent variables by anindependent grouping variable while controlling for a thirdvariable called the covariate multiple covariates can be useddepending on the sample sizeLevel and Measurement of the VariablesIn MANCOVA assumes that the independent variables arecategorical and the dependent variablesare continuous or scale variablesCovariates can be either continuous ordinal ordichotomousc Similarities and differences between simple mediationand moderationBoth mediation and moderation have to do with checking on how athird variable fits into that relationship For the purposes ofunderstanding these two concepts this is where the similaritiesendModeration is a way to check whether that third variableinfluences the strength or direction of the relationship between anindependent and dependent variable An easy way to remember this isthat the moderator variable might change the strength of arelationship from strong to moderate to nothing at allIt is almost like a turn dial on the relationship as you changevalues of the moderator a statistical relationship that youobserved before might dissolve away For example if you expectedthat the length of time studying related to the grades on acalculus test you would probably be right Lets say there is astrong relationship between time spent studying and gradesHowever that relationship may not hold true across the boardsomething like grade level might be a possible moderator If youswitch the value of this moderator from college student toelementary    See Answer
