A box and whisker plot sums up a list of numbers in one shape: the box spans the middle half of the values, the line inside is the median, the whiskers reach out to the rest, and dots mark the outliers. It is the quickest way to compare spread between groups, such as delivery times per courier, test scores per class or prices per shop. Type the group name in the first column and its raw numbers across the row; add columns with the Column button when a group has more values. There is no need to work anything out first.
The quartiles are found by linear interpolation between the sorted values, the same method as Excel's QUARTILE.INC. The whiskers end at the last value within 1.5 times the interquartile range beyond the box, and anything further out is drawn as an outlier circle. With Values on, the median is printed next to each box. Groups can have different numbers of values; empty cells are ignored.
Paste rows from Excel or Google Sheets into the top-left cell, one group per row, or drop a CSV file on the page. To see every single value rather than the summary, a scatter plot shows them all; to compare only averages, use a bar graph. Every type is on the chart maker.

The minimum, the first quartile, the median, the third quartile and the maximum. The box plot draws the middle three as the box and the whiskers reach toward the ends, stopping short of outliers.
A value more than 1.5 times the interquartile range below the first quartile or above the third is an outlier and is drawn as a circle.
No. Each row can hold as many values as it has; empty cells are skipped.
