What is a percentile in statistical terms?

• A. A specific value that 50% of data equals or exceeds
• B. A value that a given percentage of data is equal to or less than
• C. The average of the top 25% of data
• D. A measure of variation in data

Answer: (B)

A percentile in statistical terms represents the value below which a given percentage of observations in a dataset falls. For instance, the 25th percentile indicates that 25% of the data points are below this value. This concept is crucial in understanding the distribution of data, as it allows for the comparison of an individual data point within the context of the entire dataset. By recognizing that a percentile denotes a cutoff point for a specific percentage of data, it becomes clear how it informs decision-making in various fields, such as market pricing, where understanding how a specific salary compares to the broader market can be vital. The other options, while related to data analysis, do not accurately define what a percentile is. For example, the first choice describes the median rather than a percentile, as it specifically refers to the point where half the data is above and half is below. The third option refers to a specific subset of data (the top 25%), which is not a definition of a percentile. Finally, the last option discusses variation, which does not relate to the concept of percentiles, as percentiles are focused on the ranking of values rather than their spread.
