One-sample t statistic
t=(sample mean-null)/sqrt(sample variance/n). Report two-sided95% Student interval; no one-sided mode.
Degrees of freedom
t=(sample mean-null)/sqrt(sample variance/n). Report two-sided95% Student interval; no one-sided mode.
Two-sided p value
t=(sample mean-null)/sqrt(sample variance/n). Report two-sided95% Student interval; no one-sided mode.
95% sample mean interval lower
t=(sample mean-null)/sqrt(sample variance/n). Report two-sided95% Student interval; no one-sided mode.
95% sample mean interval upper
t=(sample mean-null)/sqrt(sample variance/n). Report two-sided95% Student interval; no one-sided mode.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. t=(sample mean-null)/sqrt(sample variance/n). Report two-sided95% Student interval; no one-sided mode.
