Which of the following is the mathematical average of a set of scores?

Question

BlackTom AI · Accepted Answer

In this question, we are asked to identify which option represents the mathematical average of a set of scores.
Option 1: mode. The mode is the value that occurs most frequently in a dataset, not the average of the values, so this is about frequency rather than averaging.
Option 2: median. The median is the middle value when the data are ordered from smallest to largest; it summarizes a central tendency differently than the arithmetic mean, so it is not the average in the common sense of computing the mean.
Option 3: mean. The mean is the arithmetic average, calculated by summing all the scores and dividing by how many scores there are; this is the classic definition of the mathematical average.
Option 4: standard deviation. The standard deviation measures how spread out the values are around the mean, not the central value itself, so it does not represent the average.
