For ungrouped data, remembering the following rules is quite helpful in finding out the three M’s : Mean Add all the data elements and divide the sum by number of data elements. What you get is Mean. Median Arrange all the data elements in ascending order. The data element placed exactly at the
In statistics, that single value is called the central tendency and mean, median and mode are all ways to describe it. To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value
The median is defined as the measure of the central term, when the given terms (i.e., values of the variate) are arranged in the ascending or descending order of magnitudes. In
mean, median, mode, and trimmed mean should be made. If the outliers are only to one side of the mean, the If the outliers are only to one side of the mean, the median is a better measure of location.

In statistics, a central tendency (or measure of central tendency) is a central or typical value for a probability distribution. It may also be called a center or location of the distribution. Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s. The most common measures of central tendency are the arithmetic mean, the median
Median Middle value of rank ordered data Value that separates the higher half of a data set from the lower half

This example has one mode (unimodal), and the mode is the same as the mean and median. In a symmetrical distribution that has two modes (bimodal), the two modes would be different from the mean and median.

To summarize, generally if the distribution of data is skewed to the left, the mean is less than the median, which is often less than the mode.
The arithmetic mean, geometric mean, median and mode are some of the most commonly used measures of statistical mean. They make sense in different situations, and should be used according to the distribution and nature of the data.
Averages. In statistics, an average is defined as the number that measures the central tendency of a given set of numbers.

It is widely believed that the mean is right of the median under the right-skewed distributions and left of the median in left-skewed distributions, but the median definitely is always between the mode and mean (Agresti and Finlay, 1997 Agresti, A., Finlay, B. (1997).
