Question

Examples for three types of errors, personal, systematical and random error.

Answer 1

Answer:

Systematic Error

• A worn out instrument. For example, a plastic tape measure becomes slightly stretched over the years, resulting in measurements that are slightly too high,
• An incorrectly calibrated or tared instrument, like a scale that doesn’t read zero when nothing is on it,
• A person consistently takes an incorrect measurement. For example, they might think the 3/4″ mark on a ruler is the 2/3″ mark.

Random Error

Random error (also called unsystematic error, system noise or random variation) has no pattern. One minute your readings might be too small. The next they might be too large. You can’t predict random error and these errors are usually unavoidable
