Quizplus · Accepted Answer

The best choice for comparing and combining scores from data sets with different ranges is using their respective z-scores. Z-scores standardize the scores from different data sets by converting them into the same scale, with a mean of 0 and a standard deviation of 1. This allows for a fair comparison and combination of scores from different data sets.
