Quartiles: Quartiles are the three values that divide a dataset into four equal parts, with the first quartile (Q1) being the 25th percentile, the second quartile (Q2) being the 50th percentile (the median), and the third quartile (Q3) being the 75th percentile.
Interquartile Range (IQR): The interquartile range is the difference between the third quartile (Q3) and the first quartile (Q1), and it provides a measure of the spread or variability of a dataset.
Box Plot: A box plot is a graphical representation of a dataset that displays the five-number summary: the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value.
