Challenge Problems
Push your limits with advanced challenges
You have three neighboring stations with recorded rainfalls of 110 mm, 120 mm, and 115 mm. If one station is missing data during a similar season, use the Arithmetic Mean Method to estimate the rainfall.
💡 Hint: Remember to sum and divide by the number of stations.
Consider a scenario where one station's normal rainfall is significantly higher than the others by 30%. Explain how you would apply the Normal Ratio Method to estimate its missing data.
💡 Hint: Think about how to establish the ratio effectively.
