Consider a contingency table with two rows and eight columns

Consider a contingency table with two rows and eight columns. View a table of critical values of X2.

Find the degrees of freedom _______

The critical value for a= .01 is _______

The critical value for a= .05 is _______

Solution

Step 1: The degrees of freedom is (number of rows-1)*(number of columns-1)=7

Step 2: According to the table, alpha=.01 and DF=7, critical value=18.48

Step 3: Alpha=.05 and DF=7, critical value=14.07
