From the Probability dropdown box in the calculator, you can choose any of eight cumulative probabilities: P( T ≤ t ) This is the probability that a random t-score from the t distribution will be less than or equal to the value t. P( T ≥ t ) This is the probability that a ra...

This is calculator for the T-Distribution. If you need to work with the normal distribution, you may be also interested in our z-distribution calculator . Also, a normal probability for samples could come in handy to deal with things like the Central Limit Theorem and things like that. Ap...

However, the cdf of the t-distribution is given by a somewhat complicated formula. To find the p-value by hand, you would need to resort to statistical tables, where approximate cdf values are collected, or to specialized statistical software. Fortunately, our t-test calculator determines the ...
How to use the p-value calculator Select the relevant distribution: Normal distribution, T distribution, Chi-square distribution, or F distribution Choose the relevant tail; the default is two tails. Enter the significance level (α); the default is 0.05. Input the score which is the statistic...
P Value from T Score CalculatorThis should be self-explanatory, but just in case it's not: your t-score goes in the T Score box, you stick your degrees of freedom in the DF box (N - 1 for single sample and dependent pairs, (N1 - 1) + (N2 - 1) for independent samples), ...
Binomial distribution calculatorThe binomial distribution calculator and binomial score calculator uses the binomial distribution.The binomial distribution is a discrete distribution, that calculates the probability of getting a specific number of successes in an experiment with n trials and p (probability of...
{n_2-1}}$$ For a hypothesis test that has null hypothesis $H_0 : \mu_1 = \mu_2$, we use the variable $$t=\frac{(\bar X_1-\bar X_2)}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}$$ To obtain the critical values or P-value we use the t-table. ...
This gives us a t-value of 2.57583. So this is how t-distribution works. With the hypothesis testing method, sample size, and significance level, we can find the t-value for a given data set. To use this calculator, a user simply enters in the hypothesis testing method (either ...
