The test statistic is {eq}\chi^{2}=0.264+0.021+0.913+0.048+0.264=1.51. {/eq} For a Chi-Square distribution with 5-1=4 degrees of freedom, we compute the p-value using an online calculator (such as https://www.statology.org/chi-square-p-value-calculato...
Use of the 2-SampFTest function on a TI-84 Plus CE calculator, which carries out the desired F test, then tells us that F_{35,35} = 2.35 p-value = 0.0133 < 0.05, which implies that the two population variances are different. Thus, we will use the version of the two independent ...

The next step is to find the p-value for the test statistic. The p-value is a measure of how “surprising” or “unlikely” some statistic would be given the particular assumptions that the analyst makes. In the case of these t-tests for differences in means, the p-value is the proba...
Our McNemar's test calculator will return the p-value, based on which you can decide if your findings are significant at the desired significance level. Additionally, for tests based on the χ² test statistic, our McNemar's test calculator displays the value of test statistic so that you ...
How to calculate p-value in the context of a z-test? The answer depends on whether you are using a two-tailed, a left-tailed or a right-tailed test. Say you have the calculated z-statistic,ZobsZ_{obs}Zobs. For a two-tailed test, the p-value is computed as:p=Pr(Z>∣...
Using the same aforementioned example, we get the Yates chi-square test statistic of χyates2=11×5−1×5−2222×2212×10×16×6 χyates2=2.905 Looking up this value in a chi-square table or using the Excel function =CHIDIST(2.905, 1) we get the p-value of 0.0883. Using 0.05 as...
This Fisher's exact test calculator computes both the one-tailed and two-tailed p-value for a Fisher's exact test on any 2 x 2 contingency table. To compute the p-value of other statistical tests, visit our p-value calculator. Not sure what Fisher's exact test is? Are you wondering ...
