MANCOVA (Multivariate Analysis of Covariance) is the correct choice because it allows for the analysis of multiple dependent variables (in this case, speed and accuracy) while controlling for one or more covariates (in this case, the base skill of the individual subjects). This makes it suitable for the researcher's needs to test the significance of differences in means across three age groups while accounting for the potential confounding variable.
