Challenge Problems
Push your limits with advanced challenges
If a set of observations yields the following residuals: [-2, 3, 1], calculate the total sum of the squared residuals and explain why this is significant for adjustments.
💡 Hint: Recall how squaring helps in error calculations.
A geospatial study consists of observations with variances: 1, 2, and 4. If you find that the high variance observations may mislead, how would you adjust them?
💡 Hint: Consider why variance matters in weighting.
