A) The degree of freedom in a bivariate table indeed refers to the number of cells for which the expected frequencies can vary independently. This concept is crucial in statistical analysis, particularly in chi-square tests, where it helps in determining the distribution of the test statistic under the null hypothesis.C) The degree of freedom concept helps in compensating for distortions in a bivariate table, including cases where one cell might be over or undersampled. It does so by limiting the number of independent pieces of information that can vary, thus adjusting for the sample size and the structure of the table.
