Answer 1

A Chi-square test can tell you information based on how you divide up the data

you can assume a different null hypothesis for a Chi-square test.

The Chi Square Test is a statistical test includes three types of analysis,

They are:-

1. Goodness of fit

2. Test for homogeneity

3. Test of Independence

These tests can be used to determine if a certain null hypothesis can be rejected in hypothesis testing.

Goodness of fit : It helps in identifying the sample having some particular distribution or not. The sample is evaluated which was drawn from the specified population.
Test for homogeneity : This helps in addressing various propositions with respect to the different populations having similar homogeneous features.
Test of Independence : This helps in determining the null hypothesis and find whether the population is independent of each other and having any association among them or not.
