Reply To: What is standard deviation?
I’m glad you responded & you are right:). Standard deviation is a good predictive calculation that is intended to represent the total population of a normal distribution. Scotchmo’s string #2 is not a normal distribution – I suspect he knows this. However, it is a very clever & extreme example where standard deviation provided what appears to be better information versus ES.
As always, I need to be more clear in my writing. I prefer ES for a gun that I have verified has a normal distribution. Flyers will happen and influence ES – your point is accurate & conceded.
Now I’m no expert on the varying shot string characteristics of the PCP airgun world, but I do know (as most member do) MV is important for accuracy – especially as target distance increases. So, if one has a gun that shots a normal distribution & longer range accuracy is important, what statistical measure would you put more priority on?
