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 ...
The goodness-of-fit chi-square test can be used to test the significance of a single proportion or the significance of a theoretical model, such as the mode of inheritance of a gene. A reference population is often used to obtain the expected values. Suppose the frequency of an allele ...

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.
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...

Find Critical Value or P-Value: Based on the degrees of freedom and chosen significance level, find the critical value from the chi-square distribution table or compute the p-value. Draw Conclusion: Compare the calculated chi-square statistic with the critical value or p-value. If the calculat...
What is the critical value for a chi-square test with 7 degrees of freedom at the 5 percent level of significance (p-value = 0.05)? If the chi-square statistic were 15.05, what would you conclude regarding the null hypothesis? Explain ...
