The Chi-Square is used in two circumstances as below:

i) When the researcher want to estimate how closely the observed distribution matches the proportions that is expected. This is called ‘goodness of fit’ test.

ii) When the researcher wishes to estimate whether random variables used are independent.

Assumptions of the Chi-Square Test:

i) To use Chi-Square test for independence, the two variables that are used must be of categorical data i.e. the data ought to be measured at nominal or ordinal levels. Furthermore, the two variables used ought to be composed of at least two categorical and independent groups (Brooks, 2008).

For instance, social features such as religion, political differences, ethnical differences, etc. Therefore, I will come up with two hypotheses. Afterward, I will choose the significance level, calculate the test value then compare this to the critical value. If the test value is less than the critical value, I will not reject null hypothesis. However, if the test value is larger than the critical value, I will reject the null hypothesis.
