Central Tendency

What is Central Tendency?

Central Tendency is a term used in statistics and databases, it describes the central position of data within a dataset. The central tendency can be referred to as a central location, it is actually the mean value (average) of values in a dataset. Mean is the major measuring term in central tendency where median and more are also used.

How does Central Tendency work?

The mean is the most used valid measurement method in central tendency. It is performed by taking the sum of all values in a dataset and dividing it by the number of values in that dataset. The median is the middle value in a magnitude-wise arranged dataset. The mode is the value appearing most of the time in a dataset.

Types and Examples:

If a dataset has 5 values, 11, 22, 33, 44, 55. The mean would be taken by Mean= (11 + 22 + 33 + 44 + 55)/5. To find Median, if the values are 22, 33, 44, 11, 55; we'll arrange these values by magnitude like 11, 22, 33, 44, 55. The middle value 33 is the median. The mode is the most appearing value in a dataset.
