Think about how averages are usually calculated.
List the formula used for the Arithmetic Mean Method.

What is the formula for calculating mean precipitation using the Arithmetic Mean Method?
Recall the definition of arithmetic mean.
True or False: The Arithmetic Mean Method is suitable in regions with significant rainfall variability.
Think about when averages can be misleading.
In a region with five rain gauges measuring rainfall of 3 mm, 8 mm, 10 mm, 15 mm, and 20 mm, calculate the mean precipitation and discuss how the results would differ if one gauge recorded an extremely high value.
Evaluate the effect of extreme data on averages.
You are estimating the mean precipitation for an area using the Arithmetic Mean Method, but you notice that one gauge is located in a drier microclimate. Discuss the implications of including or excluding its data in your calculations.
Think critically about the significance of spatial variability.
