21.14. Performance Metrics and Evaluation

Try these first

1. 1.

   What are accuracy metrics in soil sampling?

   Hint

   Think about how errors could affect sample quality.

2. 2.

   List one factor that impacts operational metrics.

   Hint

   Consider what makes a system efficient.

3. 3.

   Which of the following is NOT an accuracy metric?

   • Depth Precision
   • Time per Sample
   • Sensor Calibration Drift

   Hint

   Focus on what metrics deal with precise measurements.

4. 4.

   True or False: Reliability metrics measure the time a system can operate without failure.

   • True
   • False

   Hint

   Think about what reliability means in a practical sense.

5. 5.

   How would you evaluate the reliability of an automated soil sampling robot in a field with varying soil types?

   Hint

   Consider variable conditions affecting performance.

6. 6.

   Design an experiment to measure the accuracy of depth precision in automated soil sampling.

   Hint

   Think about testing against controlled standards.
