Here we have defined the p-value calculator to help you out to measure one side as well as two-sided p-values from the following distributions, normal distribution (z-Stat), t-student, chi-squared, and F stat. P-values are commonly used in science but some people find this concept intimidating. In this article, we are going to make this concept easy for everyone. We are not only going to define p-values but also teach you how to interpret the results quickly. Further, we have created the p-value calculator to make calculations easy for you. What is the p-value? If the H0 (null hypothesis) of a study question is valid, the P-value is the probability of finding the observed, or more extreme, results. The term 'extreme' and its concept

# Critical Value Calculator

Welcome to our automated Critical Value Calculator, here you can estimate the critical value for one-tail and two-tail tests quickly. It works for any test that follows normal distribution i.e. Z-test. t-test, Chi-Square test, and F distribution test. Ways to reject or accept the Null Hypothesis There are two ways to assess in hypothesis testing whether there is enough data from the study to reject H0 or to accept H0. Comparing the p-value with a pre-specified value of alpha (α) is the most common way, where alpha (α) is the probability/likelihood of rejecting H0 when H0 is valid/true. However, the estimated value of a test statistic can also be contrasted with the critical value. In this article, we are going to discuss
