Question

Coefficient of deviation is calculated by the formula:

• A. $\frac{\overline{X}}{\sigma }\times 100$
• B. $\frac{\overline{X}}{\sigma }$
• C. $\frac{\sigma }{\overline{X}}\times 100$
• D. $\frac{\sigma }{\overline{X}}$

Answer 1

The correct option is C $\frac{\sigma }{\overline{X}}\times 100$

It is a fundamental concept.
coefficient of deviation $=\frac{\sigma }{\overline{x}}\times 100$
where $\sigma$ and $\overline{x}$ are standard deviation and mean respectively.
