The box plot looks like a rectangle, often called the box, which indicates the interquartile range.
The “whiskers” extending from the box show the range of data, excluding the outliers.
The box plot was first introduced by the mathematician John Tukey in 1970.

It also covers how box plots can help you analyze data and how to interpret one.
What Information Do Box Plots Tell You?
Instead, they function to give a visual representation based on the median and quartiles.
This makes them useful for comparing data across different groups or conditions.
Box Plot Orientation
Box plots can be presented horizontally and vertically.
They are often presented vertically inprofessional academic papers.
Why Are Box Plots Helpful in Analyzing Data?
Box plots have a number of important uses and benefits in conveying and analyzing data inpsychology research.
These graphic representations can quickly convey important information about the spread and symmetry of a distribution.
Using these tools, it is possible to create visual comparisons of different groups of data.
Researchers also suggest that box plots can help people improve their ability to interpret and understand complex information.
This allows people to reason more effectively aboutquantitative information.
Box plots can also be a good alternative to histograms.
Make Comparisons
Box plots can be used to compare distributions between different groups or categories.
That does not mean that box plots are always the best choice for presenting data.
