Chi-square distribution, showing X 2 on the x-axis and P-value on the y-axis. A chi-squared test, also referred to as test (or chi-square test), is any statistical hypothesis test in which the sampling distribution of the test statistic is a chi-square distribution when the null hypothesis is true.hen T has a chi-square distribution with n â 1 degrees of freedom. For example if the sample size is 21, the acceptance region for T for a significance level of 5% is the interval 9.59 to 34.17.
The chi square test is used to test a distribution observed in the field against another distribution determined by a null hypothesis. Being a statistical test, chi square can be expressed as a formula.When written in mathematical notation the formula looks like this : When using the chi square test, the researcher needs a clear idea of what is being investigating. It is customary to define the object of the research by writing an hypothesis.Chi square is then used to either prove or disprove the hypothesis.Back to the Index. Requirements. Prior to using the chi square test there are certain requirements that must be met. These are 1  :-. The data must be in the form of frequencies counted in each of a set of categories.hi square is then used to either prove or disprove the hypothesis. Back to the Index. Requirements.
