2.2. Establishing Standards

Try these first

1. 1.

   What is the difference between true value and measured value?

   Hint

   Consider which value reflects accuracy.

2. 2.

   Define 'standard' in the context of measurements.

   Hint

   Reflect on how we relate measurements to known values.

3. 3.

   What is the role of a standard in measurements?

   • Provide a known reference for accuracy
   • Introduce errors into measurements
   • Alter the true value
   • None of the above

   Hint

   Think about how standards help in verifying accuracy.

4. 4.

   True or False: Calibration is not necessary for all measurement instruments.

   • True
   • False

   Hint

   Remember the relationship between measurement accuracy and instrument calibration.

5. 5.

   If you found that a standard weight designed to be 5 grams consistently reads 4.7 grams on your balance, how would you interpret this discrepancy?

   Hint

   Consider both the instrument and the quality of the standard.

6. 6.

   Create a detailed plan to establish a new standard for measuring water contamination levels in a specific area. What steps would you take?

   Hint

   Think about consultation, testing, and revisions.
