The ratio of standard deviation and square root of number of observations is called:

Approximately, the coefficient of variation for the given data where Pearson's second measure of skewness = 0.42, arithmetic mean = 86 and median = 80, is:

The median of the set \(\{x+1, x+2, x+3, x+4, x+5, x+6\}\), is:

Approximately, the given data where Pearson's second measure of skewness = 0.33, arithmetic mean = 116 and median = 105, then find standard deviation and coefficient of variation?

In a frequency distribution, if the mean and median are 10 and 9 respectively, then its mode is approximately:

The relation between, AM, GM and HM is:

If the mean of a certain set of data is 16 and variance is 4 then find the coefficient of variance.

The median for the given frequency distribution is:

The standard deviation of the set {18, 23, 14, 3, 17} is:

If the standard deviation and the mean of 16 values are 15.6 and 20.5 respectively then find the coefficient of variation of the 16 values.
