What is the exact meaning of the p value in the chi square test
Chi-square is a statistical test commonly used to compare observed data with the data you would expect to obtain according to a specific hypothesis. Usually, when looking at a Chi-Squared test you are using the assumption of 95% confidence, or an alpha value of .05, that is where your 0.05 comes from. If you get a value of 0.04 or 4%, you can say one of two things: a) You accept the hypothesis. b) The null hypothesis is valid through 96% confidence or an alpha level of 0.04.
