The chi-square test of independence is used to determine if there is a significant relationship between two nominal variables. The chi-square test of independence can be used to examine this relationship. The null hypothesis for this test is that there is no relationship between gender and empathy.
Given data is appropriate for testing of hypothesis to test chi-square test for independence of attributes. Because it is a small sample test.(n<30)
False
The critical value of chi-square table is doesn't based on 8 degrees of freedom.
Because it is not a chi-square for single variance it is a chi-square for independence of attributes.
In independence of attributes the degrees of freedom is (r-1)(c-1)=(3-1)(3-1)=4 degrees of freedom.
Where r= number of rows
c=number of columns.
So, that is the reason it doesn't based on 8 degrees of freedom. so , it is false.
