In statistics, these are the counts predicted by a hypothesis test for categories in a contingency table, based on the distribution assumptions of the test.

Chi-square Statistic

The Chi-square statistic is a measure used in statistics to compare observed data with data expected under a specific hypothesis, often used in tests of independence.

Expected Frequencies

Predicted counts of occurrences across different categories based on a statistical model.

Chi-square Statistic

A measure used in statistics to analyze the independence of two categorical variables and assess how likely it is that any observed difference between sets occurred by chance.
