Answer: representative data
When designing an experiment a benefit of larger sample sizes would be more representative data. This larger sample size would lead to perfect result.
In practice it is enough to simply angle the thermometer towards the direction of the ear canal. More specifically you are trying to target the direction of the tympanic membrane located in the middle ear (one of the parts of the ear; the other parts being outer and inner)
Some maneuvers, although not completely necessary, may include pulling the ear lobe upwards and outwards for babies. This is to straighten the ear canal and is more often done when using otoscopes. For adults, we pull the ear downward and outward.
I think it just shows how many people care about the cause and think it’s important. It can also raise money and awareness about it.
