Which term refers to the middle score in a distribution; half the scores are above it and half are below it?

• A. Mean
• B. Median
• C. Mode
• D. Axis labels

Answer: (B)

The middle value of a data set when the scores are arranged from smallest to largest is called the median. It splits the data so that half the scores lie below it and half lie above it. If there are an even number of scores, the median is the average of the two central values, which becomes the dividing point between the two halves. This is different from the mean, which is the arithmetic average of all the scores and can be pulled toward extreme values. It’s also different from the mode, which is the most frequent value in the set. Axis labels aren’t related to central tendency; they describe parts of a chart, not the data’s center. Example: For 3, 7, 9, 12, 15, the median is 9. With an even set like 3, 7, 9, 12, the median is the average of 7 and 9, which is 8.
