Answer:

3

Step-by-step explanation:

The interquartile range (IQR) is the difference between the upper quartile (Q₃) and the lower quartile (Q₁).

In a box plot:

  • The left edge of the box represents the lower quartile.
  • The right edge of the box represents the upper quartile.

From inspection of the given box plot:

  • lower quartile (Q₁) = 15
  • upper quartile (Q₃) = 18

Therefore:

IQR = Q₃ - Q₁

      = 18 - 15

      = 3

So the interquartile range of the given box plot is 3.
