Question

determining the range of dot plots
highlands
the dot plots show rainfall totals for several spring storms in highland areas and lowland areas.
what is the range of rainfall for the highland storms?
lowlands
what is the range of rainfall for the lowland storms?

Explanation:

Step1: Recall range formula

Range = Maximum - Minimum

Step2: Find maximum and minimum for highlands

For highlands, from the dot - plot, minimum rainfall is 2 mm and maximum is 32 mm.

Step3: Calculate range for highlands

Range = 32 - 2 = 30 mm

Step4: Find maximum and minimum for lowlands

For lowlands, from the dot - plot, minimum rainfall is 2 mm and maximum is 28 mm.

Step5: Calculate range for lowlands

Range = 28 - 2 = 26 mm

Answer:

The range of rainfall for the highland storms is 30 mm.
The range of rainfall for the lowland storms is 26 mm.
