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:
This calculator will tell you the observed power for a one-tailed or two-tailed t-test study, given the observed probability level, the observed effect size, and the total sample size. Please enter the necessary parameter values, and then click 'Calculate'. ...
Sample Size Calculator Help Statistics Dictionary Statistics Formulas Statistics Notation Statistics Problems In the dropdown box, select the statistic of interest. Enter a value for degrees of freedom. Enter a value for all but one of the remaining textboxes. ...
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.
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,...
Enter either the p-value (represented by the blue area on the graph) or the test statistic (the coordinate along the horizontal axis) below to have the other value computed. Student's t-distribution Other distributions:Normal•Chi-square•F ...
88 Methylation β values for CpG sites were calculated and values were input into a DNA Methylation Age Calculator30 to predict epigenetic biomarkers for aging (DNAm PhenoAge) and aging acceleration, determined by the correlation between DNAm PhenoAge and chronological age (DNAm PhenoAgeAccel, ...
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...
