Daily living skills (DLS) standard scores as a function of balance and full scale IQ. Balance was found to significantly interact with IQ to predict DLS, suggesting that balance and DLS were related only in those with lower IQ scores. To illustrate the nature of this interaction, we performed a median split for IQ (median=104) and plotted the relation between balance and DLS in those with higher and lower IQs. However, we also used color to demonstrate individual differences in IQ, as IQ was used as a continuous variable in all of the analyses. The points on the scatterplot are adjusted for the main effect of age, as age was a significant predictor in the model.
