What statistical term is used to describe the midpoint value in a set of ordered data?

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

Answer: (C)

The midpoint value in a set of ordered data is known as the median. To find the median, the data set must first be arranged in ascending or descending order. If the number of observations is odd, the median is simply the middle number in that ordered list. If the number of observations is even, the median is calculated by taking the average of the two middle numbers. The median is particularly useful in statistical analysis because it is less affected by outliers and skewed data than the mean, making it a better measure of central tendency in such situations. This characteristic of the median allows it to represent the central point of a data set more accurately when extreme values are present.
