For variables measured at the interval-ratio level, the preferred measure of central tendency is the mean. This is because the mean takes into account all the values in the distribution and provides the average value, which can be useful for understanding the typical value of the variable. The mode and quartile are less precise measures of central tendency and are better suited for variables measured at the ordinal or nominal level. The decile is also less commonly used as a measure of central tendency, and is more useful for dividing a distribution into segments.
