Challenge Problems

Push your limits with challenges.

Question 1

A rainfall database shows discrepancies between two nearby rain gauges. After analyzing, you find the old slope is 1.8, new slope is 1.2, and the original rainfall recorded was 90 mm. Correct the rainfall data using the Ratio Method.

💡 Hint: Remember to apply the Ratio Method formula.

Question 2

You have observed rainfall data from a nearby station that has historically recorded values inconsistent with nearby data. After regression, you find coefficients a=10 and b=0.5. If the observed value from this station is 20 mm, calculate the corrected value.

💡 Hint: Plug those values into the regression equation.
