What does the box plot show about the variability of the heights?

A box plot illustrates the variability of heights by displaying the range, interquartile range, and potential outliers. The length of the box indicates the interquartile range, highlighting where the middle 50% of the data lies, while the "whiskers" show the spread of the data outside this range. If the whiskers are long or there are many outliers, it suggests greater variability in heights. Conversely, a shorter box and shorter whiskers indicate less variability among the heights.
