    Question

    While conducting a chi-square test to examine the

    independence of attributes in an m x n contingency table, what formula determines the degree of freedom?
    A m (n-1) Correct Answer Incorrect Answer
    B n (m-1) Correct Answer Incorrect Answer
    C (n-1) Correct Answer Incorrect Answer
    D (m-1) (n-1) Correct Answer Incorrect Answer

    Solution

    In a contingency table with m rows and n columns, the degrees of freedom for a chi-square test to determine independence is calculated as (m-1)(n-1). This accounts for the number of categories minus one in each dimension, allowing for the calculation of expected frequencies under the assumption of independence.
