1.12. Various Errors in Measurements

Try these first

1. 1.

   Define natural errors in measurements.

   Hint

   Think of weather changes.

2. 2.

   What is meant by instrument error?

   Hint

   Consider tools used in surveying.

3. 3.

   What type of error arises from environmental conditions?

   • Natural Error
   • Systematic Error
   • Personal Error

   Hint

   Think about how weather can affect measurement.

4. 4.

   True or False: Systematic errors can always be corrected.

   • True
   • False

   Hint

   Consider what makes these errors different.

5. 5.

   A surveyor consistently receives measurements for a straight line that are off by 5 centimeters due to a stretched measuring tape caused by heat exposure. How can the surveyor determine the systematic error present, and which corrective action should they take?

   Hint

   Consider how temperature affects materials and what calibration means.

6. 6.

   A state requires accurate elevation measurements above the sea level, but the surveyors reported vastly different numbers at the same point, leading to significant discrepancies. Describe potential sources of both systematic and random errors.

   Hint

   Think about equipment maintenance and human factors in measurement tasks.
