From the prices of shares X and Y given below: Find out which is more stable in value:
Given, Data is given in the form of two table
To Find: Find out which one is more stable in value
Explanation: Let’s Find for Value X
Now, N=70
=48
SD (X)=
SD (X)==9.9
Coefficient of variation =
Coefficient of variation = = 20.6
Let’s Find for Value Y
Now, N=10
=105
SD (Y)=
SD (Y)==2
Coefficient of variation =
The coefficient of variation = = 1.90
Hence, Cv for Y is smaller that Cv of X, So X is more stable that y.
