Explanation:
Detailed explanation-1: -The quartiles data into three points-a lower quartile, median, and upper quartile-to form four groups of the dataset. Along with the minimum and maximum values of the data set, the quartiles divide a set of observations into four sections, each representing 25% of the observations.
Detailed explanation-2: -If a group of numbers is divided evenly into four parts, the number that falls between the first and second fourth is the first quartile. Scientists also refer to the fourths themselves as first, second, third and fourth quartiles. A quartile is a type of quantile, which divides up a set into equal parts.
