A) time to stop the analysis

D) time to increase the size of the table
E) time to reduce the size of the table by combining categories

Question

When the frequency in any cell of a contingency table is low, it is advisable to reduce the size of the table by combining categories. This is known as collapsing categories, and it helps to increase the sample size in each cell, making the results more reliable. Option A is not the best choice because stopping the analysis may not give a complete picture of the relationship between the variables. Option B is not the best choice because ignoring low frequencies can lead to inaccurate results. Using the phi coefficient (Option C) is not a robust method, and collapsing categories is often a better solution. Increasing the size of the table (Option D) may not be feasible or practical, and it can lead to spurious results.
