Using 95% confidence interval calculator To use our tool: Look at the calculator panel on the left side of the screen. First, fill in the sample mean (average) - x̅. Now, fill in the standard deviation (s).
95% Confidence Interval The 95% confidence interval is a statistical method used to estimate the scope within which a population parameter, like the mean, is likely to lie. To simplify the computation of the 95% confidence interval, a confidence interval calculator can be extremely useful. ...
