In statistics we define the term mean . Now What is a Mean? It is the part of the mathematics in which we define the central value for the given set of data values .Mean is a concept that define the one value that represent the whole set in terms of single value .Sometimes it is also called as the average for the given set of data .When we talk about the average of the values is also known as the arithmetic mean that is define as the sum of the all values in the given data set that is divided by the number of values in the data set .
If there is five values in the given data set that are n1 , n2 , n3 , n4 and n5 then the average or arithmetic mean is defined as the formula
Mean = sum of all values / number of values = (n1 + n2 + n3 + n4 + n5 ) / 5 .
If we talk about the types of mean then there are three types of mean in the statistics that are named as:
(I) : arithmetic mean
(II) : geometric mean
(III) : harmonic mean
As we discuss above normally arithmetic mean is define as the average value or standard average.
When there is talk about the geometric mean then it is calculated by multiplying all the terms .This types of mean are used for calculation of growth rates.
Geometric mean g = ( ∏n i=0 g i ) 1 / n .
When some relation is define between the units of set of numbers then there will be use harmonic mean.
When we talk about the use of the mean it is mainly helps in probability that is also known as the mean in probability. for more information on mean visit here
