Question 21

When considering errors in measurement you can unconditionally state what four facts about measurement error. (List 2)

Answer 21

1. No measurement is exact.

2. The true value is never known.

Question 22

Define Natural Error

Answer 22

Caused by variation in wind, temperature, humidity, atmospheric pressure, refraction, gravity, and magnetic declination.

Question 23

Define Instrumental Error

Answer 23

Result from imperfections in equipment.

Question 24

Define Blunder

Answer 24

A significant mistake due to human error.

Question 25

Describe the difference between systematic errors and accidental error.

Answer 25

Accidental errors are usually small, random, and avoidable, while systematics errors are repetitive and constant(caused by errors in the surveying equipment).

Define Precision

Answer 27

Refers to the refinement or consistency of a group of measurements

Question 28

Define Accuracy

Answer 28

The absolute nearness of measured quantities to their true values.
