Challenge Problems
Push your limits with challenges.
Question 1
A researcher measures three known masses (1g, 5g, 10g) using a poorly calibrated balance. The reported weights were 0.9g, 4.8g, and 9.5g. What does this indicate about the calibration of the balance?
💡 Hint: Compare the reported weights with the true values to assess the degree of inaccuracy.
Question 2
An instrument's calibration shows an R-squared value of 0.85 for a linear fit but varies widely in measurements compared to a benchmark. Discuss potential reasons and implications for the instrument performance.
💡 Hint: Consider factors that can affect instrument readings beyond just the calibration itself.
