Question 1

What is the formula for calculating mean precipitation using the Arithmetic Mean Method?

  • P_mean = P_1 + P_2 + P_3
  • P_mean = (P_1 + P_2 + P_3) / 3
  • P_mean = (P_1 + P_2 + P_3) / n

💡 Hint: Recall the definition of arithmetic mean.

Question 2

True or False: The Arithmetic Mean Method is suitable in regions with significant rainfall variability.

  • True
  • False

💡 Hint: Think about when averages can be misleading.

Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Evaluate the effect of extreme data on averages.

Question 2

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.

💡 Hint: Think critically about the significance of spatial variability.
