Question
Chapter 1, Problem 22Q
Interpretation Introduction
Interpretation:
The difference between random error and systematic error has to be outlined.
Concept Introduction:
Random error and systematic error are the types of Observational errors. An error is basically meant as the difference between the actual value and the calculated value obtained through experiment.
Random errors are occurred when the measurements in each count of the experiments varies randomly. Systematic errors are occurred when the error follows certain constant pattern of deviation.
