Answer:
Chi-squared statistical test
Explanation:
Chi-squared statistical test is used in categorical data. The chi-squared statistical test is used for testing the amount by which the expected counts differ from the observed counts.
The chi-square distribution provides a good approximation to the sampling distribution of the chi-square statistic if the expected count in each cell is five or higher.
Large values of the chi-square statistic indicate that One should be suspicious of the null hypothesis.
