It supports nominal level measurements.It uses the contingency tables (or crosstabs) to summarize the relationship between various categorical variables. ![]() It determines how well an assumed distribution fits the data.It evaluates whether observed frequencies vary significantly from the expected frequencies under a given set of assumptions. ![]() ![]() The features of the chi-square test are listed as follows: The Characteristics of the Chi-Square Test For example, one needs to determine the reason behind variations of health plans across age groups. There are cross-tabulations (two-way tables) and the relationship between various categorical variables needs to be studied.There are two categorical variables and the relation between them is to be determined.The formula for calculating the expected frequency in the i th row and j th column is given as follows: The Uses of the Chi-Square Test for Independence “E ij”is the expected frequency in the i th row and j th column.“O ij” is the observed frequency in the i th row and j th column.The formula of the chi-square test for independence is given as follows: read more of one variable is not affected by the other. In simple words, its calculation shows the possible outcome of an event with the relative possibility of occurrence or non-occurrence as required.

The symbol of the chi-square test is “x 2” (i.e., “x” raised to the power 2). In other words, it shows how well the sample data fits a set of observations.
