what is chi square test in research methodology ?

The chi-square test is a statistical approach used in research methodology to decide whether or not there’s a great association among specific variables. It compares the determined frequencies of occurrences in distinct categories with the anticipated frequencies primarily based on a null hypothesis. The test is usually used in pass-tabulated records to assess the relationship between  or more variables. If the chi-square price is significant, it shows that the variables are not independent and there’s a correlation between them. The chi-square test is extensively implemented in social sciences, biology, and marketplace studies.
