Box and whisker plots are a way to visualize data by showing the median, quartiles and range of your data. It's great for making comparisons between different sets of data. It's a useful tool to help you identify outliers in your data.

Box and Whisker Plot: A graphical representation of a data set that divides the data into quartiles, and includes lines extending from the box (called whiskers) showing the maximum and minimum values. Quartiles: A quartile is a type of quantile which divides the number of data points into four equal parts, or quarters. The first quartile is the data point at which one quarter of the data lies below it, and three quarters lie above it. Interquartile Range (IQR): The interquartile range (IQR) is the range of the middle 50% of the data. The IQR is calculated by subtracting the first quartile from the third quartile.
