18 kwi 2019 · Learn three methods to calculate the p-value for a hypothesis test based on a t statistic: online calculator, t distribution table, and TI-83 or TI-84 calculator. See examples and steps for each technique with a right-tailed test.
22 sty 2020 · t = (x-μ) / (s/√n) where x is the sample mean, μ is the hypothesized mean (in our example it would be 15), s is the sample standard deviation, and n is the sample size. Once we know the value of t, we can use statistical software or an online calculator to find the corresponding p-value.
17 sty 2023 · The first way to find a p-value from a t statistic is to use an online calculator like the T Score to P Value Calculator. We can simply enter the value for t and the degrees of freedom, then select “one-tailed”, then click the “Calculate” button: The corresponding p-value is 0.08662.
The following formulae say how to calculate p-value from t-test. By cdf t,d we denote the cumulative distribution function of the t-Student distribution with d degrees of freedom: p-value from left-tailed t-test: p-value = cdf t,d (t score) p-value from right-tailed t-test: p-value = 1 − cdf t,d (t score) p-value from two-tailed t-test:
Learn how to calculate a p value for any hypothesis test using a general process and a step-by-step example of a t-test. Find out how to identify the test statistic, specify the sampling distribution, and place the test statistic in the distribution to find the p value.
