WebStatistics Standard Error ( SE ) - The standard deviation of a sampling distribution is called as standard error. In sampling, the three most important ... WebIf the sample size is large (say bigger than 100 in each group), the 95% confidence interval is 3.92 standard errors wide (3.92 = 2 × 1.96). The standard deviation for each group is obtained by dividing the length of the confidence interval by 3.92, and then multiplying by the square root of the sample size:
