Chi squared test a hypothesis testing method in which observed frequencies are compared with expected frequencies for experimental outcomes In hypothesis testing data from a sample are used to draw conclusions about a population parameter or a population probability distribution The chi-squared distribution is obtained as the sum of the squares of k independent, zero-mean, unit-variance Gaussian random variables. Generalizations of this distribution can be obtained by summing the squares of other types of Gaussian random variables.

Chi Square FormulaSolution: Now calculate Chi Square using the following formula: χ 2 = ∑ (O − E) 2 / E Calculate this formula for each cell, one at a time. For example, cell #1 (Male/Full Stop): Observed number is: 6 Expected number is: 6.24 Therefore, (6 – 6.24) 2 /6.24 = 0.0092 Chi square formula is a statistical formula to compare two or more statistical data sets It is
