Question

What are systematic and statistical possible sources of error when using a multimeter? (when measuring resistance in a circuit)

Answer 1

Answer #1

The main sources of systematic error

1.effect of environmental disturbances, often called modifying inputs

2.disturbance of the measured system by the act of measurement

3.changes in characteristics due to wear in instrument components over a period of time

4.resistance of connecting leads

The main sources of statistical error

1.sampling

2. measurement

3. estimation

4 hypothesis testing

5. reporting.
