Chi-Square test application 1: Test Goodness of a fit. We use the goodness of a fit to test if the observed categorical data follows the hypothesized or expected distribution. Example 1: P-value Interpretation Suppose f_exp are the expected number of boys in grade 1 different classes. f_ob...

chi-square test n. A test that uses the chi-square statistic to test the fit between a theoretical frequency distribution and a frequency distribution of observed data for which each observation may fall into one of several classes. American Heritage® Dictionary of the English Language, Fifth ...
Interpretation:The chi-square test produces a p-value that indicates the probability of observing the data if the variables are independent. A small p-value (typically less than 0.05) suggests that there is a significant association between the variables. ...
Chi-Square test is a statistical hypothesis for a given set of categorical data. Learn its p-value, distribution, formula, example for categorical variables, properties, degree of freedom table here at BYJU'S.
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…

This calculator performs a two-tailed chi-square test and assumes a P value significance threshold of 0.05. The results page also includes the chi-squared statistic and its degrees of freedom. Notice the category names are not involved at all in the interpretation. Seethis examplefor help with...
X-squared = 1.7444, df = 1, p-value = 0.1866 p-value Interpretation of Chi-square test To interpret the chi-square test we use p-value. If the p-value is less or equal to 0.05 then we may reject the null hypothesis that means the categorical variables are independent. The p-value ...
