Select Sample Screen ShotsArea 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. | Paired t-test
 When data are matched or in pairs (usually the same subject responds to two different conditions), the paired t-test provides more power than the between subjects t-test | 2-Sample t-test
 Enter either summary data or raw data (not shown) to quickly look for significant differences. The calculator provides p-values for equal or unequal variances, confidence interval around the difference and a graph that updates automatically. | Home Page
