This section defines the three most common measures of central tendency: the mean, the median, and the mode. The relationships among these measures of central tendency and the definitions given in the previous section will probably not be obvious to you.
However, if this is not possible, then there are situations in which the mean, median, and mode have their specific advantages. The mean is ordinarily the preferred measure of central tendency. The mean is the arithmetic average of a distribution. The mean presented along with the variance and the standard deviation is the best measure of central tendency for continuous data. There are some situations in which the mean is not the best measure of central tendency. In certain situations, the median is the preferred measure.
