Birch et al found a threefold difference in the magnitude of the coefficient of variation for energy intake at eating occasions compared to daily energy intake in a controlled setting,1 and we observed a similar threefold difference among children in their everyday environment.2 Dr Goldman points out that averaging individual measurements reduces the variability of the mean. It was for this reason that we used a statistical test to compare the observed coefficient of variation for the day's energy intake to the expected coefficient of variation for the day.
