Margin of Error Calculator

In statistics, the margin of error (e) is defined as the radius of the confidence interval. It is an absolute quantity. Calculation of margin of error varies for different confidence percentage. When a population is not completely sampled, margin of error calculation is needed. Find the e value using this calculator based on the standard error of a sample and the critical value.

Formula:

M = C x E
Where, C = Critical Value E = Standard Error of the Statistics M = Margin of Error

Example:

If critical value is 10 and SE is 3,

M = C x E

= 10 x 3
= 30
Margin of error is 30
