 Area under t-distribution Use the t-conversion calculators if you need to find the critical value for a percent or to see if a t-statistic is statistically significant. Simply enter the sample size and degrees of freedom to get the area or inverse area under the t-distribution. t-Confidence Interval Confidence intervals show both the precision and location of a sample estimate. Enter either summary or raw data and specify the confidence level. A graph automatically updates to show a visualization of the confidence interval. 1-Sample t-test If you need to compare a mean against a criterion (e.g. can people withdraw money from an ATM in less than 30 seconds) use the 1-sample t-test for raw and summary data.

The calculator provides p-values for equal or unequal variances, confidence interval around the difference and a graph that updates automatically.
