We can invoke this to substitute the point estimate for the standard deviation if the sample size is large "enough". However you will need an estimate of the population standard deviation. This can either be determined by a preliminary sampling programme, or estimated from .

Learn about the qualitative and quantitative differences between the sample and population standard deviations.

At the 95% confidence level, the confidence interval is given by μ±1.96σ/√n where μ is the mean, σ is the standard deviation and n is the . This statistics video tutorial explains how to calculate the sample size given the confidence level and margin of error. At the 95% confidence level, the confidence interval is given by μ±1.96σ/√n where μ is the mean, σ is the standard deviation and n is the . See a worked out example that goes through the steps to calculate the standard deviation of a sample.
