Data Insights from Box Plots
To read a box plot correctly, pay attention to the following points:
- If the box is short and the whiskers are short, this may indicate that the data is concentrated in a narrow range and has few outliers:
- If the whiskers are long, this may indicate a large scatter of data and the presence of outliers:
- If the median is offset from the center line of the box, this may indicate a skewed distribution:
Finding points behind the whiskers helps identify outliers and potential anomalies in the data.
