chi square test is divide into two types
for first degone The degrees of freedom for the chi-square are calculated using the following formula: d f= (r-1)(c-1)
where r is the number of rows and c is the number of columns. in column categorical variables are denoted. Chi-square test is designed to analyze categorical data. That means that the data has been counted and divided into categories.
for second method df= n-1
where n is number of categories.

The Chi-Square Table (Chapter 17) The chi-square table: The degrees of freedom for a given test are listed in the column to the far left; the level of significance is listed in the top row to the right. These are the only two values you need to find the critical values for a chi-square test.
