How the one samplettest calculator works Prismcalculates thetratio by dividing the difference between the actual and hypothetical means by the standard error of the actual mean. The equation is written as follows, where x is the calculated mean, μ is the hypothetical mean (specified value), S...
Directions for using the calculator are listed below, along with more information about two samplettests and help on which is appropriate for your analysis. NOTE: This is not the same as a one samplettest; for that, you need thisOne samplettest calculator. ...
This calculator will tell you the one-tailed and two-tailed probability values of a t-test, given the t-value and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'. Degrees of freedom:
The t-distribution calculator makes it easy to compute thecumulative probabilityassociated with at scoreor with a sample mean. For help in using the calculator, read theFrequently-Asked Questionsor review theSample Problems. To learn more about Student's t-distribution, go to Stat Trek'stutorial...
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.Please enter the necessary parameter values, and then click 'Calculate'.Degrees...
Use the t critical value calculator to find the critical value of t, f, & chi-square if you don’t know how to find critical value.
For most T-distribution questions, you’ll usually be given all of the information you need to plug into the calculator and retrieve the T score. You might be asked to find the area under a T curve, or (like Z scores), you might be given a certain area and asked to find the T sc...
If anything is unclear, frequently-asked questions and sample problems provide straightforward explanations. The calculator is free. It can found in the Stat Trek main menu under the Stat Tools tab. Or you can tap the button below. T Distribution Calculator ...
Note that this calculator is strictly addressing the question of alpha robustness to non-normality. Power is not considered here. If the minimum sample size requirements cannot be met, you should use a nonparametric equivalent to the parametric hypothesis test (i.e. One Sample Sign or Wilcoxon,...
