Which descriptive statistic identifies the midpoint of ordered data?

Question

Options

• AMean
• BMedian
• CMode
• DRange

• A
  2% (1)
• B
  93% (51)
• C
  4% (2)
• D
  2% (1)

Explanation

Median is correct because it is defined as the middle value of a dataset when all values are arranged in ascending or descending order - making it literally the midpoint of ordered data. If there is an even number of values, it is the average of the two middle values.

• Mean (A) is the arithmetic average (sum divided by count), which considers all values equally and is not necessarily the middle position.
• Mode (C) is the most frequently occurring value - it has nothing to do with order or position.
• Range (D) is a measure of spread (max minus min), not a central value at all.

Memory tip: Think "median = middle" - both start with "med-", just like the median strip down the middle of a road.
