Multiple Choice Question For a chi-square test with more than two categories, what is the accepted limitation on the use of a chi-square test? O 20% of the cells must have frequencies of 5 or more. O No more than 20% of the cells can have expected frequencies less than 5. O No more than 20% of the cells can have observed frequencies less than 5.

In chi-square tests, the conventional and conservative rule, known as the Rule of Five, is to require that: degrees of freedom for the test be at least five. observed frequency for each cell be at least five. difference between the observed and expected frequency for each cell be at least five. expected frequency for each cell be at least five.

Possibly the most important thing to watch out for when doing a Chi-square is that: a.) all of your cells have an observed frequency greater than 5. b.) none of your cells has an expected frequency less than 5. c.) your means are normally distributed. d.) all of your observations are dependent on each other.

Given below is the number of possible values for two variables of a population. One of the assumptions for the chi-square independence test states that "At most 20% of the expected frequencies are less than 5." Determine the maximum number of expected frequencies that can be less than 5 in order for that assumption to be satisfied for these two variables. Note: The number of cells for a contingency table with m rows and n columns is m • n. two and three The maximum number of expected frequencies that can be less than 5 is .
