subject: Sample Mean Calculator [print this page] Introduction to sample mean calculator: Introduction to sample mean calculator:
In general, the arithmetic mean or simply the mean or average of n observations x_1, x_2 x_n is defined to be the number means of x such that the sum of the deviation of the observation from mean of x is 0. Sample mean is calculated by using calculator. Calculator is used to do the process easily and reduce the wastage of time in doing through calculations. We have to enter the values at the area given to enter the value to find the mean value and press the calculate button. Then the mean is calculated instantly.

Example Problem for Sample Mean Calculator:
Mean is calculated under the formula as,
'bar (x)= (sum_ (i = 1) ^n (x_i))/N'
Let us see some examples to perform the mean operation for the given values.
Problem for sample mean calculator: Calculate the mean value of five students marks given 10, 11, 20, 83, and 91
General formula for calculating means is,
'bar (x)= (sum_ (i = 1) ^n (x_i))/N '
Whereas,
i =1 is the initial value for the given variable
n - No of terms in the given experiment.
'sum_ (i = 1) ^n = (10 +11 + 20 +83 + 91) / 5'
' = 215 / 5'
'= 43'
Problem for sample mean calculator: Calculate the mean value of the products in the market in which the value of the products are given 20, 30, 50, 90, 80, and 66
