The total number of scores in a frequency distribution is found by summing which quantity?

Explanation:
In a frequency distribution, each row shows a score value and how many times that score occurs (its frequency). The total number of scores is the sum of all these frequencies, because you’re counting every observation once across all score values. If you added the actual scores themselves, you’d be getting the total sum of all scores, not the count of observations. If you multiplied each score by its frequency and then added, you’d still get the total sum of all scores. Squaring the scores isn’t relevant here. So, the total number of scores equals the sum of the frequencies.
