Use this calculator to compute a two-tailed P value from any Z score, T score, F statistic, correlation coefficient (R), or chi-square value. Once you have obtained one of these statistics (from a publication or even another program) the P value helps interpret its statistical significance...
Use our p-value calculator to easily find a left-tailed, right-tailed, or two-tailed p-value for a z-score, t-score, chi-square, or f-value.
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), ...
A t-distribution is defined on n-1 degree of freedom. The shape of the t-distribution will be normal if and only if the sample size is enough large. t-distribution will be used when population standard deviation is not known. The p-value...
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. ...

Here are the steps you need to follow to obtain the p-value of your sample with the 365 P-Value Calculator: Determine the distribution of the test statistic under the null hypothesis. For example, if you are conducting a t-test, the test statistic will follow a t-distribution with n-1...
P value or the calculated probability, is the best probability to provide the smallest level of significance at which the null hypothesis is not true.
If you need to derive a r score from raw data,you can find a Pearson (r) calculator here. How to report Pearson'sr(APA) R Score: N: Significance Level: 0.01 0.05 0.10 Enter your values above, then press "Calculate". Correlation Calculators ...
