Answer :

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.
