What is the middle value when data are arranged in order?

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

Answer: (A)

The middle value when data are arranged in order is the median. When you line up all observations from smallest to largest, the median sits right in the center, cutting the dataset into two halves with an equal number of values on each side. If there’s an odd number of observations, the median is exactly the middle data point; if there’s an even number, the median is the average of the two central values. This measure is especially useful because it isn’t tugged toward extreme values (outliers) the way the mean can be. In contrast, the mode is the most frequent value, the mean is the arithmetic average, and skewness describes how asymmetrical the distribution is rather than a single central value.
