The covariate in analysis of covariance must be measured as a scale variable, as it is a continuous variable that is being used as a predictor in the analysis. Nominal and ordinal variables are not appropriate as covariates in this type of analysis, as they do not provide meaningful linear relationships with the outcome variable. Integer variables may be scale variables, but not all integers are scale variables (e.g. number of siblings is an integer but not a scale variable).
