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.
