How to use the One-sample t Statistic Calculator
Use independent observations and a reference mean chosen for the question of interest. The sample standard deviation uses n−1.
The calculation
Worked example
Observations 8,10,12 compared with reference 9 give t≈0.866 and two degrees of freedom.
Assumptions and limits
Returns only the statistic and degrees of freedom, not a p-value or decision. A t-distribution interpretation requires suitable assumptions; zero sample variation is rejected.
