Can you get a negative chi square statistic?
The characteristics of the chi-square distribution are: A. The value of chi-square is never negative. B. The chi-square distribution is positively skewed. C. There is a family of chi-square distributions.
What conclusion is appropriate if a chi-square test produces a chi-square statistic near zero?
A chi-square statistic which is near zero suggests that the observations are exceptionally consistent with the hypothesis.
Chi-square test properties and importance?
square
What is the underlying principle of a chi square test?
The underlying principle is that the square of an independent Normal variable has a chi-square distribution with one degree of freedom (df). A second principle is that the sum of k independent chi-squares variables is a chi-squared variable with k df.
What does the number that Chi-Square produces represent?
It is the value of a random variable which has a chi-square distribution with the appropriate number of degrees of freedom.

Negative?
A chi square probability of 0.05 means what?
If your chi square test has a probability of 0.05 or less it is likely, but not certain, that your hypothesis is not correct.
What does the number that Chi-Square produces represent?
It is the value of a random variable which has a chi-square distribution with the appropriate number of degrees of freedom.
Is Chi-square a test of association?
The Chi-squared statistic can be used to test for association.
