Do you have a memory aid to help remember the key differences between sensitivity and specificity? Please comment below!

(1) SPIN = if test is highly SPecific ... rule IN if get positive result (2) SNOUT = if test is highly Sensitive ... rule OUT if get negative result ... I think this is right (I got this from Therapeutics Education Collaboration podcast ... The College of Family Physicians of Canada).

SPpIN: high SPecificity + Positive result -> rule IN tested positives SNnOUT: high SeNsitivity + Negative result -> rule OUT tested positives Spin snout.

A false negative would be okay if the alarm was very affordable. I would rather have the inconvenience and risk of a few false negatives than not have the alarm and have the car stolen. Even worse would be if chop shops started popping up all around the country, and the Center for Car Safety failed to approve a car alarm that people can afford, because they felt it wasn't sensitive enough. All in the name of consumer safety.
