This simple confidence interval calculator uses a t statistic and sample mean ( M) to generate an interval estimate of a population mean (μ). As you can see, to perform this calculation you need to know your sample mean, the number of items in your sample, and your sample's standard deviation. t for confidence interval Enter the degrees of freedom and push "calculate" to compute the value of t to for the specified level of confidence. Push a radio button to change the level of confidence. Performs unpaired t test, Weldh's t test (doesn't assume equal variances) and paired t test. Calculates exact P value and 95% confidence interval. Clear results with links to extensive explanations. Calculates exact P value and 95% confidence interval. This calculator will tell you the Student t-value for a given probability and degrees of freedom. Student t-values for both one-tailed (right-tail) and two-tailed probabilities will be returned. Student t-values for both one-tailed (right-tail) and two-tailed probabilities will be returned. Confidence interval calculator. Calculate the confidence interval of the mean and the standard deviation using Normal distribution or T distribution for the mean and Chi-Square distribution for the standard deviation.
