Question

An FDA agent inspect shipment weights of soda bottles to identify the following: (1) incorrect entries that were intentionally made to increase the shipment weights and (2) incorrectly recorded weights of shipments. Disucss whether each probem involves randome or systematic errors.

Do incorrect entries that were intentionally made to increase the shipment weights involve random or systematic errors?

A. Random, because the cause of the error affects all measurement in the same way.

B. Random, because they represent an unpredictable event in the measurement process.

C. Systematic, because the cause of the error affects all measurements in the same way.

D. Systematic, because they represent an unpredictable event in the measurement process.

Answer 1

The correct answer is

C. Systematic, because the cause of the error affects all measurements in the same way.

in point 1) incorrect entries that were intentionally made to increase the shipment weights If this is intentional then it is done in order to create a fraud by making more money by predicting more weight than actual.

Thus, this is systematic error

Note:

If it is not intentional then it will be classified as Random error as there is no direction (i.e weight can be more or less)
