The correct answer is: Hundred equal parts.

Explanation

Percentiles are a statistical measure used to indicate the relative standing of a value within a data set. Specifically, the term "percentile" indicates that the data set is divided into 100 equal parts, with each part representing 1% of the data. For instance, the 25th percentile (often referred to as the first quartile) indicates that 25% of the data points fall below this value. Similarly, the 50th percentile corresponds to the median, which divides the data set into two equal halves. Thus, the use of percentiles is crucial in understanding the spread and relative standing of data in statistical analysis.
