Standard Deviation Formula Confidence Interval at Trevor Stites blog

Standard Deviation Formula Confidence Interval. To calculate a confidence interval, take the critical value (z or t) and multiply it by the standard error of the mean (sem). The general formula for a confidence interval for the mean μ μ, assuming a normal distribution and known variance, is: The formula and method of estimating confidence interval depends on whether the population’s standard deviation is known on not. S is the standard deviation; ¯x ±zα/2 ⋅ σ √n x ¯ ± z α / 2. Formula for confidence interval for \(\sigma\) is: This value is known as the margin of error (moe). The confidence interval is based on mean and standard deviation.
