Chi-square is a non-parametric test, i.e., it does not require normal distribution or variance assumptions about the populations from which the samples are drawn. The general purpose of the…
Non-parametric Test: The chi-square test is a non-parametric test, meaning it doesn’t make assumptions about the underlying distribution of the data. Limitations of the Chi-Square Test The chi-square test assumes categorical data and independence of observations, potentially leading to unreliable ...
The chi-square (χ 2 ) is a non-parametric procedure used to test hypotheses about the independence of frequency counts in various categories. For example, the data may be the proportions of smokers preferring each one of three brands of low-tar cigarettes or the proportion of people ...

We have described three separate uses of the chi-square distribution: comparing observed and expected frequency distributions of a nominal variable, testing for the independence of two variables, and using the chi-square test in determining correlation coefficients. We hope this paper has helped you ...
The Chi-Square Test is the widely used non-parametric statistical test that describes the magnitude of discrepancy between the observed data and the data expected to be obtained with a specific hypothesis.
Chi-Square Test Definition Before an experiment is conducted, a researcher must first develop a hypothesis, which declares a testable potential explanation for some outcome of interest. However, when a hypothesis is created, a null hypothesis must come along with it. A null hypothesis is a statem...
