Quizplus · Accepted Answer

A weighted mean is used when each score has a different weight, meaning that some scores contribute more or less to the final calculation of the mean. A disproportionate set of scores refers to a set of scores where the number of scores in each group is not equal. Therefore, the best choice is the weighted mean. The other options, mean, median, and mode, are calculated using different formulas and do not take into account the weights or disproportionate set of scores.
