While P values can beeasy to misinterpret, they are the most commonly used method to evaluate whether there is evidence of a difference between the sample of data collected and the null hypothesis. Once you have run the correctttest, look at the resulting P value. If the test result is ...
Welcome to our t-test calculator! Here you can not only easily perform one-sample t-tests, but also two-sample t-tests, as well as paired t-tests. Do you prefer to find the p-value from t-test, or would you rather find the t-test critical values? Well, this t-test calculator ca...

p-Value Calculator for the Student t-Test
The paired t-test calculator calculates the paired t-test p-value. When you enter raw data, the paired t-test calculator also calculates the Shapiro-Wilk normality test and calculates the outliers. Enter raw data directly Enter raw data from excel ...
Use our t-test calculator to perform one-sample or two-sample t-tests and calculate the p-values. Plus, the formulas both tests.
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), ...
Our Student's t-test calculator can do one sample t tests, two sample paired t-tests and two sample unpaired t-tests. Results page will give you t-Score, standard error of difference, degrees of freedom, two-tailed p-value, mean difference and confidence range. You can choose the confide...
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 hypothesis-testing procedure is calledthe non-pooled t-test. The t-table is available in ...
t-Test Calculator is a tool used to determine whether there is a statistically significant difference between the means of two independent groups. What is a t-Statistic? The t-Statistic is a value derived from your sample data that measures the size of the difference relative to the variation...
