The median is the point on a distribution at which 50% of values fell above and below; identified by first rank ordering the values.

The median is the point on a distribution at which 50% of values fell above and below; identified by first rank ordering the values.

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

Answer: (A)

The main concept tested is identifying the measure that splits a data set into two equal halves when values are ordered. The median is the middle value when you line up all observations from smallest to largest, so exactly half lie below it and half above it. If there are an even number of observations, the median is the average of the two central values, and this still represents the point that divides the data into two halves. This property makes the median a robust descriptor of central tendency in terms of a 50% split, especially when the data are skewed or contain outliers. The mean, by contrast, is the arithmetic average and can be pulled toward extreme values, so it doesn’t necessarily sit at the halfway point of the ordered data. The mode is simply the most frequent value and does not relate to a 50% division, and the range measures how spread apart the data are, not where the center lies. Therefore, the described statement correctly identifies the median.
