What is the point on the scale that has an equal number of scores above and below it?

• A. Mean
• B. Range
• C. Mode
• D. Median

Answer: (D)

The point that divides a data set into two equal halves is the median. It is defined so that there are as many scores below it as above it. When there is an odd number of scores, the middle value serves this role directly. When there is an even number of scores, the median is the average of the two middle values, and that average still creates a split where half the scores lie at or below and half at or above. This makes the median a robust measure of central tendency, especially for skewed data or ordinal scales, because it depends on order rather than the exact numerical values. For example, in a set like 1, 2, 3, 4, 100, the median is 3, yielding two values below and two above, whereas the mean would be heavily influenced by the extreme 100.
