CHISQ.TEST()/CHITEST()

Syntax. CHISQ.TEST(actual_range,expected_range)

Definition. This function returns the test statistic of a χ2-test for independence. CHISQ.TEST() returns the value from the chi-squared (χ2) distribution for the statistic and the appropriate degrees of freedom. You can use c2-tests to determine whether hypothesized results are verified.

Arguments

  • actual_range (required). The range of data that contains observations to test against expected values

  • expected_range (required). The range of expected observations

Note

If actual_range and expected_range have a different number of data points, the function CHISQ.TEST() returns the #N/A error.

The c2-test first calculates a c2-statistic by using the following formula:

where

  • Aij = actual frequency ...
