Mean
What is it?
This refers to the middle or average number as it appears within a group of numbers.
According to , the mean is the average of the numbers; in other words, it is the total of the numbers divided by how many numbers there are. (, 2014)
Note that Mean is calculated by adding all the numbers together and dividing by the number of numbers. Sometimes the mean is the actual middle occurring number, but often it is a number which does not occur naturally within the set of numbers (Green, 2016).
