3.1. Calibration Curve Dynamics

Try these first

1. 1.

   What is the true value in measurements?

   Hint

   Think of what you would consider the correct measurement.

2. 2.

   What is a standard?

   Hint

   Recall what we discussed about trusted values.

3. 3.

   What does a calibration curve represent?

   • The relationship between weight and volume
   • The relationship between instrument response and actual measurements
   • The statistical method for data analysis

   Hint

   Remember the main purpose of calibration curves.

4. 4.

   True or False: Standards are not important in measurement.

   • True
   • False

   Hint

   Think about why we use standards.

5. 5.

   Suppose you have a calibration curve that appears to have a non-linear fit. How would you approach re-evaluating your instrument's accuracy?

   Hint

   Consider whether your ranges of measurement are adequate.

6. 6.

   You noticed that your calibration curve shifted significantly after a week of use. What factors could contribute to this shift, and how might you ensure consistent reliability in your future measurements?

   Hint

   Think about what you learned about the variability over time.
