The standard deviation is the preferred measure of dispersion for age data. It provides a measure of the spread of the data around the mean, and is commonly used in statistical analysis. The other options (mean, average deviation, and quartile deviation) are measures of central tendency or other measures that are not appropriate for describing the variability of the data.
