Now, we are ready to use theT Distribution Calculator. Since we have already computed the t statistic, we select "t score" from the drop-down box. Then, we enter the t statistic (-0.4276) and the degrees of freedom (13) into the calculator, and hit the Calculate button. The calculato...
This distribution calculator determines the Cumulative Distribution Function (CDF), scores, probabilities between two scores, and PDF or PMF for the following distributions: Normal, Binomial, Student's t, F, Chi-Square, Poisson, Weibull, Exponential, and Uniform. ...
As shown in Figure 2, the "t distribution" calculator can be used to find that 0.086 of the area of a t distribution is more than 1.96 standard deviations from the mean, so the probability that M would be less than 1.96sM from μ is 1 - 0.086 = 0.914. ...

T distribution is used to make assumptions for a mean when the population standard deviation is not known to us and the sample size is small. Learn completely here at BYJU’S.
If $X$ is a normally distributed variable then for independent samples of sizes $n_1$ and $n_2$ from the two populations, the variable $$t=\frac{(\bar X_1-\bar X_2)-(\mu_1-\mu_2)}{s_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}}$$ has the t-distribution with $df = n...
This calculator will compute the probability density function (PDF) for Student's t-distribution, given a t-value and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'. Degrees of freedom:
T-distribution and t-scores A t-score is the number of standard deviations from the mean in a t-distribution. You can typically look up a t-score in a t-table, or by using an online t-score calculator. In statistics, t-scores are primarily used to find two things: The upper and ...
Below you will find descriptions and links to 23 different statistics calculators that are related to the free cumulative distribution function (cdf) calculator for the t-distribution. The related calculators have been organized into categories in order to make your life a bit easier. ...
