Question

Which of the following example(s) does NOT cause bias in a research study.

Answer 1

(A) The internal body temperature can be taken from any area of the body without a difference in the type of temperature, resulting in NO bias. Of course this is completely reliant on the type of illness, but out of all options this is correct.

Illnesses affect the throat/mouth and ear.
checking the thermometer underneath a tongue will result in the same temperature as the ear, in an ill individual.
