Understanding Box-and-Whisker Plots

A box-and-whisker plot provides a visual summary of the distribution of a data set. It shows the median, quartiles, and potential outliers. The box represents the middle 50% of the data, with the median as the center line. The whiskers extend to the smallest and largest values that are not outliers. Outliers, if any, are represented as individual points. Overall, this plot helps to analyze the spread and skewness of the data, making it a valuable tool for understanding the distribution of numerical data.
