29 sie 2023 · The Chi-square test is a non-parametric statistical test used to determine if there’s a significant association between two or more categorical variables in a sample. It works by comparing the observed frequencies in each category of a cross-tabulation with the frequencies expected under the null hypothesis, which assumes there is no ...
The chi-squared statistic is a single number that tells you how much difference exists between your observed counts and the counts you would expect if there were no relationship at all in the population.
The chi-square test calculator can be used as a goodness-of-fit calculator by entering the observed values (counts) in the first column and the expected frequencies for each outcome in the second column.
