Box Plot Calculator
Box Plot Calculator: A Box Plot, or Box-and-Whisker plot, is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. It provides a visual representation of data variability and can highlight outliers.

FAQs
What is a Box Plot?
A Box Plot summarizes a data set using five key statistics: the minimum, first quartile (Q1), median, third quartile (Q3), and maximum. It visually displays the spread and center of the data, making it easy to identify outliers.
How do I interpret a Box Plot?
To interpret a Box Plot, look at the box, which spans from Q1 to Q3, enclosing the median line. The whiskers extend to the minimum and maximum values, showing data variability. Outliers may be indicated as individual points beyond the whiskers.
Can Box Plots show outliers?
Yes, Box Plots effectively highlight outliers, which are values significantly lower or higher than the rest of the data. Outliers are usually represented as individual points beyond the whiskers of the box plot, indicating their deviation from the overall distribution.
What types of data can I use?
You can use numerical data in any form, as long as the numbers are separated by commas. This can include test scores, measurements, or any other numerical observations suitable for statistical analysis.
Is the Box Plot Calculator free to use?
Yes, the Box Plot Calculator is completely free to use! You can input your data, calculate the box plot, and visualize the results without any charges or sign-ups required.
