We fit the data using a three-factor ANOVA model (Workstation, Size, and Distance) and included all two-factor interactions. The Workstation-Size interaction was not significant suggesting that the effect of target size is independent of posture. Removing Workstation Size interaction results in a model with all significant parameters. Table 2 contains coefficients, standard errors, t Statistics and p-values for the three-factor ANOVA model fit using multiple regression.
