Question
Chapter 1, Problem 1.50P
Interpretation Introduction
Interpretation:
The procedure that decreases the random error of a measurement is to be determined.
Concept introduction:
Precision is defined as the closeness of two measurements with each other. Accuracy refers to the closeness of the measured values to the standard or known value. Some errors also occur in the calculation of the measured quantities.
The two types of errors are as follows:
1. Systematic error: This error is a part of the experimental setup or faulty devices.
2. Random error: This error occurs always and is due to instruments’ precision.
