Question

BlackTom AI · Accepted Answer

The question asks us to identify what the 50th percentile corresponds to in a data distribution.
Option 1: 'third quartile' — This is the 75th percentile, not the 50th. A common mistake is confusing quartiles with percentiles, but by definition the third quartile marks the value below which 75% of observations fall. So this choice misplaces the percentile.
Option 2: 'mode' — The mode is the most frequently occurring value in the data set. It has no fixed relationship to percentiles or the 50th percentile, unless the data are arranged in a highly specific way, which is not a general rule. Therefore this option is incorrect.
Option 3: 'mean' — The mean is the average of all values. It is a measure of central tendency but does not correspond to a percentile, including the 50th percentile, except in perfectly symmetric distributions where the mean and median coincide. As a general statement about percentiles, this is not accurate.
Option 4: 'median' — The median is defined as the middle value that divides the ordered data into two equal halves, which exactly corresponds to the 50th percentile. In practice, half of the data lie at or below the median, and half lie at or above it, making this the correct conceptual match for the 50th percentile.
