1. The mean is the most common measure of central tendency. It simply the sum of the numbers divided by the number of numbers. The symbol m is used for the mean of a population. The symbol M is used for the mean of a sample.
The formula for M is:
M = σX/N
where σX is the sum of all the numbers in the sample and
N is the number of numbers in the sample.
Example: The mean of 7, 12, 24, 20, 19 is (7 + 12 + 24 + 20 + ...
The solution names and defines three measures of central tendency.
