... well, I think that's not entirely true, although I know perfectly well that is kind of a trend to despise statistics...
... or perhaps my teachers lied (very convincingly) about metal fatigue, loads for structural analysis, hydrology computations for bridges and traffic flow patterns.
I believe most people do not think about that when crossing a bridge, where all those statistics are put to work to ensure you will cross to the other side, even in an earthquake, while raining and in the middle of a traffic jam.
To put it in another way: "It was a heavy storm, I was driving fast, the night was mighty dark, she was reclining against me, I was drunk... and the bull was black¨.
I frequently tend to say that
if you want to know about the past, about who's to blame (
like some people in this thread, ehem, ehem), please,
hire a lawyer.
Judges are all about the past.
On the other hand,
engineering is about what we should do, not about who's to blame.
Good engineers concentrate in the future, hence, we all become statisticians... and you do not become one until you can discern your f-tests and your ANOVAs.
For example, you know, betting is about the future.
Statistics about the future, short version
So, if you believe statistics serve no purpose to understand the future, will you take a par bet on Ericsson against my bet on Hamilton?
Never tell me the odds!
