What is the variance of first 50 even natural numbers?

833
Hence the variance of the 50 even natural numbers is 833.

Can coefficient of variation be greater than 100?

All Answers (10) Yes, CV can exceed 1 (or 100\%). This simply means that the standard deviation exceed the mean value.

How do I calculate variation?

How to Calculate Variance

1. Find the mean of the data set. Add all data values and divide by the sample size n.
2. Find the squared difference from the mean for each data value. Subtract the mean from each data value and square the result.
3. Find the sum of all the squared differences.
4. Calculate the variance.

What do you mean by coefficient of variation explain the method to calculate it give its merits and demerits?

Coefficient of variation= standard deviation / mean × 100. Merits- 1)It represents the ratio of the standard deviation to the mean. 2)Compares variation from one distribution to another. 3)It’s unitless and dimensionless variable.

Can a coefficient of variation be over 100?

What is the coefficient of variation of the two distributions?
