Difference Between Standard Deviation and Standard Error

Webz is the standard deviation of z, and similarly for the other variables. (This formula, and everything which follows, extends in the natural way to functions of more than two variables.) 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:
