Standard error – Wikipedia – The relative standard error of a sample mean is the standard error divided by the mean and expressed as a percentage. It can only be calculated if the mean is a non-zero value. As an example of the use of the relative standard error…

The formulas for these two parameters are shown below: μp = π. The estimated standard error of p is therefore. We start by. In terms of percent, between 47.5% and 56.5% of the voters favor the candidate and the margin of error is 4.5%.

Standard Error is a method of measurement or estimation of standard deviation of sampling distribution associated with an estimation method. The formula to calculate Standard Error is,
