Method, example and limitations
Quartiles use R7 interpolation. Whiskers are extreme observations within Q1 − 1.5 IQR and Q3 + 1.5 IQR. Minimum and maximum may lie beyond the whiskers.
Data 0; 10; 20; 30: min=0, Q1=7.5, median=15, Q3=22.5, max=30. IQR=15. Other quartile conventions can give different results.
