|
|
2 * Standard Deviation
|
|
|
Critical Value
|
|

Explanation:
Detailed explanation-1: -Note also that the margin of error will always be larger than the standard error simply because the margin of error is equal to the standard error multiplied by some critical Z value. In the previous example, we multiplied the standard error by 1.96 to obtain the margin of error.
Detailed explanation-2: -Is the Standard Error Equal to the Standard Deviation? No, the standard deviation (SD) will always be larger than the standard error (SE). This is because the standard error divides the standard deviation by the square root of the sample size.
Detailed explanation-3: -The margin of error is equal to half the width of the entire confidence interval.
