Question

What is an example of when you would want consistent data and, therefore, a small standard deviation??

Answer 1

Suppose you are a sniper in army. You must need your data to be consistent with as small as possible standard deviation. This is the perfect example when you would want a consistent data with a small standard deviation because if the standard deviation is more, then you being a sniper will do many mistakes and this might result in saving many criminals. So, it is important in this case to keep the standard deviation as small as possible otherwise the outcome will be worse.
