How it's calculated
min, Q1 (25th percentile), median, Q3 (75th percentile), max
The five numbers show the centre, spread and skew of the data at a glance and are what a box plot draws. Quartiles and percentiles use linear interpolation between the closest ranks by default (R type 7, Excel PERCENTILE.INC / QUARTILE.INC); the median-of-halves method taught in many courses and used by TI-83/84 calculators can give slightly different values for small data sets, so it is offered as an option for quartiles.
