Answer
Both A and R are true and R is the correct explanation of A.
Explanation
Quantile is a statistical term that refers to dividing the total distribution of given data into a given number of equal proportions. Each portion is called a quantile, and it represents a specific percentage of the data set. The median divides a distribution into two equal parts, representing the middle value of a data set when the data is sorted in ascending order. A quartile divides a distribution into four equal parts, with each quartile representing 25% of the data set.
