COEFVAR function
Description
Coefficient of variation function.
COEFVAR(range) computes the coefficient of variaton of the contents of the cells in the specified range. The result is expressed as a percentage.
$$ \text{CV(%)} = 100 \times \frac{\text{SD}}{\text{Mean}} $$
$$ \text{CV(%)} = 100 \times \frac{\text{SD}}{\text{Mean}} $$ The argument range can be a list of numbers, cell addresses, cell ranges (such as A1:A10).
Range can also be a matrix. In that case the function returns a matrix with one row and the same number of columns, with each element the COEFVAR of the corresponding column. If range is a row matrix, it is converted to a column matrix first.
