## How do you find standard deviation from coefficient of variation?

If you know nothing about the data other than the mean, one way to interpret the relative magnitude of the standard deviation is to divide it by the mean. This is called the coefficient of variation. For example, if the mean is 80 and standard deviation is 12, the cv = 12/80 = . 15 or 15%.

## Why is standard deviation considered to be the most reliable measure of variability?

The standard deviation is an especially useful measure of variability when the distribution is normal or approximately normal (see Chapter on Normal Distributions) because the proportion of the distribution within a given number of standard deviations from the mean can be calculated.

## What is the constant coefficient?

Constant coefficients mean that the quantities multiplying the dependent variable and its derivatives are constants.

## What is the difference between coefficient and subscript?

Subscripts: Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element. Coefficient: A small whole number that appears in front of a formula in a balanced chemical equation.

## What does a subscript tell you in math?

Subscripts are commonly used to indicate indices ( is the entry in the th row and th column of a matrix ), partial differentiation ( is an abbreviation for. ), and a host of other operations and notations in mathematics. SEE ALSO: Superscript.

## What does the subscript tell you?

The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
