Question 73

The partially completed box plot shows the distribution of average temperatures at Heathrow in 2015.

A partially completed horizontal box plot of average temperatures at Heathrow in 2015, with a temperature axis from 7 to 29 °C.

An outlier is defined as a value more than 1.5×IQR1.5 \times \text{IQR}1.5×IQR below Q1 Q_1\,Q1​ or more than 1.5×IQR1.5 \times \text{IQR}1.5×IQR above Q3Q_3Q3​. The lowest temperature was 8∘C8^\circ\text{C}8∘C and the highest two temperatures were 24.6∘C24.6^\circ\text{C}24.6∘C and 27.1∘C27.1^\circ\text{C}27.1∘C.

Complete the box plot showing clearly any outliers, giving the exact upper and lower outlier limits.
