How do you find the Quartile of a number?
A number does not have a quartile, a set of data does.

What divides the data into four equal parts?
The data is divided into four equal parts by quartiles. The first quartile (Q1) marks the 25th percentile, the second quartile (Q2) is the median or 50th percentile, and the third quartile (Q3) represents the 75th percentile. These quartiles help to understand the distribution of the data by segmenting it into four intervals, each containing approximately 25% of the observations.
