13. Errors and Adjustments

Try these first

1. 1.

   Define systematic errors.

   Hint

   Think about how repetitive mistakes can arise.

2. 2.

   What is a gross error?

   Hint

   Consider common mistakes we make while doing tasks.

3. 3.

   What type of error is caused by human mistakes and misreadings?

   • Systematic
   • Random
   • Gross

   Hint

   Think about errors you might make accidentally.

4. 4.

   True or False: Random errors can be completely eliminated.

   • True
   • False

   Hint

   Remember that you cannot prevent all fluctuations.

5. 5.

   You perform a survey with several measurements taken at a landmark. You notice that some readings consistently fall 2 meters short of the known height. Classify this type of error and suggest how to mitigate it.

   Hint

   Consider the instruments and processes used for the measurements.

6. 6.

   A student computes the average of a set of 10 measurements that each contain random variations. Discuss how these variations might affect the average and what statistical methods could analyze the result's reliability.

   Hint

   Think about the significance of variability in datasets.
