3b. Chi squared analysis A chi-square test is also referred to X². It is a statistical test that is used to find a significant difference between the observed data to the expected data in one or more groups. To calculate a chi square you have to carry out the equation‚ X^2= ∑▒(O-E)"²" ÷E. Hₒ = this means that statistically there is no change between the observed and the expected frequencies of the results. Hₐ = this means that there is a significant change between the observed and the expected
