can you explain when I use chi square fittness of good test, homogenity test and independent test?
Chi square fitness= Its a test applied to a single categorical variable from two different populations. is used to determine whether frequency counts are distributed identically across different populations.
The sampling method should be random sampling
Homogenity Testcan be used to make a conclusion about whether two populations have the same distribution.
The population sample must be the same
All values in the table must be greater than or equal to 5.
 The two populations follow the same distribution.
 The two populations have different distributions.

IIndependent Test: Use the Test for Independence when you want to decide whether two variables are independent or dependent. In this case there will be two qualitative survey questions or experiments and a contingency table will be constructed. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses are:
 The two variables are independent.
 The two variables are dependent.
