Formula for the Chi-Square Test The formula for the chi-square test statistic depends on the type of data analyzed. Below is the formula for the chi-square test: What Do Chi-Square Statistics Tell You? Chi-square statistics are used to determine if there’s a significant association between...
The difference between the Chi-square test of homogeneity and the Chi-square test of independence lie in the manner in which the study has been designed. The Chi-square test of homogeneity compares the distribution of a single variable in two o...

All chi-square tests have a test statistic that follows a chi-square distribution. This is simply a statistical distribution, just like a normal, uniform, or Poisson distribution.
Chi Square Formula The Chi-Square is denoted by χ2. The chi-square formula is: χ2= ∑(Oi– Ei)2/Ei where Oi= observed value (actual value) Ei= expected value. The Chi-Square test gives a P-value to help you know the correlation if any!
Chi-Square Test:Used for categorical data to assess whether there is an association between two variables. Regression Analysis:Used to explore the relationship between a dependent variable and one or more independent variables. It helps predict outcomes and assess the strength of relationships. ...
