21.14.1. Accuracy Metrics

Try these first

1. 1.

   What is depth precision in soil sampling?

   Hint

   Consider why depth is necessary in soil testing.

2. 2.

   What is sensor calibration drift?

   Hint

   Think about how sensors need to be adjusted to provide accurate data.

3. 3.

   What does the term 'depth precision' refer to in soil sampling?

   • The accuracy of the sample depth
   • The time taken for sampling
   • Cost of the sampling process

   Hint

   Consider what aspect of the sampling process is being measured.

4. 4.

   True or False: Sampling reproducibility ensures that different samples yield the same results under the same conditions.

   • True
   • False

   Hint

   Think about the meaning of reproducibility.

5. 5.

   Create a detailed plan for maintaining sensor accuracy over a year-long construction project. Outline the steps including how often sensors should be calibrated.

   Hint

   Factor in project timelines and environmental changes.

6. 6.

   Design an experiment to test the effect of sampling depth on soil moisture readings. Describe your method and expected outcomes.

   Hint

   Consider the variables you want to investigate.
