During a medical examination, a thermometer placed under the armpit of a patient consistently records a temperature slightly lower than the actual core body temperature. According to the standard classification of errors in measurement, this systematic deviation is an example of:
Options
- AInstrumental error
- BError due to imperfection in experimental technique
- CRandom error
- DPersonal error
Correct answer
B. Error due to imperfection in experimental technique
Step-by-step solution
According to the standard classification of errors in measurement, systematic errors are classified into instrumental errors, imperfections in experimental technique or procedure, and personal errors.
To determine the temperature of a human body, a thermometer placed under the armpit will always give a temperature lower than the actual core body temperature. This systematic deviation occurs because the armpit is an external surface and does not perfectly reflect the internal core temperature. This is a classic example of an error due to imperfection in experimental technique or procedure.
