Mean, Median and Mode
In a big data set, there are different ways to describe the data mathematically. Mean, Median and Mode are different measures of center in a numerical set of data. These are three principal ways to designate the average value of a list of numbers.
Mean: –
The mean is the most commonly used measure of finding the average. It is very simple, just add up all the numbers in a data set and divide by the number of data entries.
Median: –
The median is also known as the middle number. It can be found by ordering all data points and picking out the one in the middle. If there are two numbers in the middle then take the mean of these two numbers.
Mode: –
The mode is the most frequent number. It is the number that occurs the highest number of times.
Example: –
If the data set is {5, 2, 4, 3, 2, 2}
Mean of this data set is = 3
Median of this data set is = 2.5
Mode of this data set is = 2
