Hypothesis testing
Hypothesis testing is conducted for the parameters of the population like population mean, population standard deviation, and so on. It is to check whether the sample values conform to the pre-stated parameter values of the original distribution or not. The hypothesis for the single population mean is conducted using the z- or t-test. The selection of the test depends upon the value of the standard deviation.
There are three types of chi-square tests:
Chi-square test of independence
Chi-square test of homogeneity
Chi-square goodness of fit test
