To find the standard deviation of the sample mean ( σX̄ ), divide the population standard deviation ( σ) by the square root of the sample size (n): σX̄ = σ/√n. Contrary to the

The following formula is used to compute the sample standard deviation: s = \sqrt {\frac {1} {n-1}\sum_ {i=1}^n (X_i-\bar X)} s = n −11 i=1∑n (X i −X ˉ)
