Ví dụ
Quartiles are particularly useful in statistics to summarize the position of values within a dataset.
Quartiles are often used in box-and-whisker plots to visually represent the distribution of a dataset.
The third quartile, Q3, marks the 75th percentile, showing the value below which 75% of the data falls.
The first quartile, Q1, marks the 25th percentile of a dataset, indicating the value below which 25% of the data falls.
Q2, the second quartile, corresponds to the median, dividing the dataset into two equal halves.
