Because of sampling error,a chi-square computed from sample data might be less than 0 even when the null hypothesis is true.

Question

Quizplus · Accepted Answer

Chi-square values cannot be negative, so if the computed value is less than 0, there must be an error in the calculation. If the null hypothesis is true, the chi-square value should be greater than or equal to 0. Sampling error may affect the accuracy of the chi-square value, but it should not cause it to be negative.
