Because "rounding by the thousand" is the correct statistical way of presenting such estimated numbers. It is completely irrelevant how "the formula works". If you have access to a statistics bureau/university teacher, they can explain it to you. All this circles around is presenting data with an accuracy that does not exist 8as we have just witnessed). @ultraslick Exactly my thoughts. |
It's not the "correct" way to present the data. It's the eaisest way to present the data to cut out a bunch of extra numbers. No more.
I graduated with a degree that involved 3 statistics classes thanks.
Doing so can lead to all kinds of errors. It's really not the best way to do it for compiling numbers.
The raw numbers tell you much much more and are more important for just about anything except having 1 pretty number to look at.
Espiecally when your adding up sales weekly and monthly. Games go on for MONTHS selling just a few thousand... rounding their MAY even out, or it may not. Seems stupid to leave something to chance when it's a moving dataset.
You think NPD has nothing but rounded by thousand numbers in their database? I'd bet not.
