What is central tendency?
See the explanation
When a large volume of numerical data is available, it is not always possible to examine every single numerical data and reach a conclusion. Hence, there is a need to reduce the data to one or a handful of numbers so that comparison is possible. It is for this purpose, we have measures of central tendency defined in Statistics. A measure of central tendency gives us one numerical value that can be used for comparison. Hence, it has to be a number which is centered around the large volume of data - a point of gravitational pull towards which every other numerical value is attracted. In such a case, the deviation of individual values from this central measure tells us whether the data is consistent or inconsistent.
