Why It's Gaining Attention in the US
A box plot displays the distribution of a dataset using a box and whiskers. The box represents the interquartile range (IQR), which is the difference between the 75th percentile (Q3) and the 25th percentile (Q1). The whiskers extend from the box to show the range of the data. The median, or the middle value, is indicated by a line within the box. The whiskers can be extended to 1.5 times the IQR to capture outliers, or unusual data points.
