1. Overview the chi-square distribution (also chi-squared or χ2-distribution) with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables. The chi-square distribution is a special case of the gamma distribution and is one of the most widely used probability distributions in inferential statistics, notably in hypothesis testing and in co..

1. Overview Probability of obtaining a sample "more extreme" than the ones observed in your data, assuming $H_{0}$ is true The p-value is one of the key outputs of analyzing data. The p-value is the probability that, if the null hypothesis were true, sampling variation would produce an estimate that is further away from the hypothesized value than our data estimate. Shortly, The p-value tells us..
