Link to what was previously discussed in Statistics (an Elementary Math E-Math topic) in Drawing & Understanding of Cumulative Frequency, here are the 5 features for a Box & Whisker Plot (I guess you would know which part represents the box, and the portion which are the whiskers)

  1. Minimum
  2. Lower Quartile, Q1
  3. Median
  4. Higher Quartile, Q3
  5. Maximum

Note the difference between these 2 terms:

Range = Max – Min
Interquartile Range (IQR) = Q3 – Q1
