Research Methodology · ANCOVA and Degrees of Freedom
Analysis of Covariance (ANCOVA) merges ANOVA with regression principles to compare group means while statistically factoring out the confounding influence of continuous covariate variables. Match the specific degrees of freedom (df) parameters of an ANCOVA model in LIST-I with their corresponding formulas in LIST-II. Assume N is the total number of observations, k is the number of groups, and c is the number of continuous covariates being statistically factored out. LIST-I (ANCOVA df Parameter) A. Between Groups B. Within Groups (Error) C. Covariates D. Total LIST-II (Formula) I. N - k - c II. c III. N - 1 IV. k - 1 Choose the correct answer from the options given below:
