Question: 1 / 530

How is the range in a distribution determined?

By adding the highest and lowest scores

By subtracting the lowest score from the highest score

In a distribution, the range is determined by finding the difference between the highest and lowest scores. This is because the range represents the spread or variability of the data in the distribution, and the highest and lowest scores contribute to this measure of spread. Adding the highest and lowest scores (option A) would result in double-counting these values and not accurately represent the range. Calculating the average of all scores (option C) or counting the number of scores (option D) would not provide a measure of spread and therefore, cannot determine the range in a distribution.
