First Box-and-Whisker Plot (Smartphone Distribution)

Step1: Identify lower extreme

The leftmost point is 28.

Step2: Identify upper extreme

The rightmost point is 55.

Step3: Identify median

The middle line of the box is 38.

Step4: Identify lower quartile

The left edge of the box is 32.

Step5: Identify upper quartile

The right edge of the box is 48.

Step6: Calculate range

Range = Upper extreme - Lower extreme
$\text{Range} = 55 - 28 = 27$

Step7: Calculate interquartile range

IQR = Upper quartile - Lower quartile
$\text{IQR} = 48 - 32 = 16$

Second Box-and-Whisker Plot (Milwaukee Temperatures)

Step1: Identify lower extreme

The leftmost point is 26.

Step2: Identify upper extreme

Step4: Identify lower quartile

The left edge of the box is 35.

Step5: Identify upper quartile

The right edge of the box is 73.

Step6: Calculate range

Range = Upper extreme - Lower extreme
$\text{Range} = 80 - 26 = 54$

Step7: Calculate interquartile range

IQR = Upper quartile - Lower quartile
$\text{IQR} = 73 - 35 = 38$
