Question

A thermometer placed under the armpit always shows a lower value than the actual body temperature. Which type of error is demonstrated in its measurement.

Answer 1

The goal is to determine the 'core temperature', the temperature of the interior of the body. The rectum and tongue are the most accessible areas of the body that are at core temperature. The area under the tongue, full of blood vessels, is almost as accurate as the rectal area, and a lot more pleasant place to use.Occasionally the armpit will be used for kids usually as it is difficult and inconvenient for them to hold the thermometer under the tongue. Inconvenient place for a child to keep the thermometer there long enough
