Table 4. Comparison of participants’ effectiveness using Cochran’s Q test.

Each row corresponds to a task-performing exercise. Each cell of the row contains the results of the participants’ effectiveness with each method for the evaluated exercise, as well as the chi-square and p-value resulting from the Cochran’s Q test. Resulting less-effective methods for each exercise are shaded in orange.
