Given : sum of squares of 10 terms is 38500, variance is 825,
To Find : coefficient of standard deviation
Solution:
Variance = sum of squares of terms/ number of terms - (mean )²
=> 825 = 38500/10 - (mean )²
=> 825 = 3850 - (mean )²
=> (mean )² = 3025
=> Mean = 55
standard deviation = √Variance
=> standard deviation = √825
=> standard deviation = 28.72
Coefficient of standard deviation is = ( SD / Mean)
= (28.72/55)
= 0.52
