Which term is a measure of center in a set of numerical data?

• A. Mean
• B. Central Tendency
• C. Mode
• D. Median

Answer: (D)

When you want a value that represents the middle of a numerical data set, you’re looking at a measure of center. The median does this by arranging the data from smallest to largest and selecting the middle value (or averaging the two middle values if the count is even). This middle position makes the median a reliable center point, especially when the data have outliers or are skewed, because extreme values don’t pull it toward one end as the mean can. The mean is also a measure of center but changes with outliers, and the mode is simply the most frequent value, which isn’t necessarily a central location. Central tendency is the overall idea of where data cluster, not a single value. Therefore, the term that best represents a center value for a set of numerical data is the median.
