Work for CV of 2, 4, 3, 5 & 6
The below workout with step by step work or calculation may help grade school students or learners to understand how to find what is the coefficient of variation for the data set 2, 4, 3, 5 & 6.
Workout :
step 1 Address the formula, input parameters and values
Input parameters and values
x1 = 2, x2 = 4, x3 = 3, . . . . , x5 = 6
Number of elements n = 5
Find CV for sample distribution 2, 4, 3, 5 & 6
step 2 Find the mean for 2, 4, 3, 5 & 6
µ =
n
∑
i = 1
Xin
=(2 + 4 + 3 + . . . . + 6)/5
µ = 4
step 3 Find the standard deviation for 2, 4, 3, 5 & 6
=√{ (2 - 4)² + (4 - 4)² + (3 - 4)² + . . . . + (6 - 4)²}/4
= √(-2)² + (0)² + (-1)² + . . . . + (2)²/4
= √(4 + 0 + 1 + . . . . + 4)/4
= √10/4
= √2.5
σ = 1.5811
step 4 Apply standard deviation and mean values in the below coefficient of variation formula
CV =σ/µ
= 1.5811/4
= 0.3953
For the sample distribution 2, 4, 3, 5 & 6
4 is the mean
1.5811 is the standard deviation
0.3953 is the coefficient of variation
