WebMay 24, 2024 · The p-value tells you, given the evidence that you have (data), if the null hypothesis looks ridiculous or not […] The lower the p-value, the more ridiculous the null hypothesis looks. The p-value is a value between 0% and 100% and can be retrieved from the null hypothesis, sampling distribution, and the data.

WebMay 20, 2024 · Revised on November 28, 2024. A chi-square (Χ2) distribution is a continuous probability distribution that is used in many hypothesis tests. The shape of a chi-square distribution is determined by the parameter k. The graph below shows examples of chi-square distributions with different values of k.
