4. Acquisition of Standards

Try these first

1. 1.

   What is a standard in measurements?

   Hint

   Remember, standards tell us what the correct measurement should be.

2. 2.

   Define calibration.

   Hint

   Think about aligning an instrument with a specific benchmark.

3. 3.

   What defines a standard?

   • A known measurement
   • Any value measured
   • An inaccurate measurement

   Hint

   Think about what we compare our measurements against.

4. 4.

   True or False: Calibration is a one-time process.

   • True
   • False

   Hint

   Does accuracy change over time or stay fixed?

5. 5.

   You have two measuring instruments that give slightly different readings for the same standard. What steps can you take to determine which instrument is more accurate?

   Hint

   Consider using reproducibility tests and verifying against external standards.

6. 6.

   A critical environmental parameter is measured over a month, but the data shows significant variation. How would you investigate this inconsistency?

   Hint

   Look for patterns or correlations in data that could indicate an issue.
