Answer:  11.8

======================================================

Explanation:

The five number summary is the set of these items, in this exact order

  1. Min = smallest value
  2. Q1 = first quartile
  3. Median = middle most number
  4. Q3 = third quartile
  5. Max = largest value

So with the five number summary 4.6, 14.3, 19.7, 26.1, 31.2, we see that

Q1 = 14.3 and Q3 = 26.1

Subtracting these two values gets us the IQR (interquartile range)

IQR = Q3 - Q1

IQR = 26.1 - 14.3

IQR = 11.8
