Is there a way to get the statistics on dice roles?

mctrivia: Of course. But what would be a purpose of that?
If one roll appears to be more used than the other ones, someone would jump and cry "the dice are not fair!".

And it will start another endless discussion and argument.

Fencer: Because I am currious. I have seen many random number generater algeritherms that have lower probability on the extreme values. I.E. 1 and 6. Ideally after several million roles they should be pretty close to falling 16% of the time. If they don't a simple fix to the lower odds of falling on the extremes is to randomly chose between 0 and 7 and re role if 0 or 7 comes up.

mctrivia: Sounds like a bug in the algorithm to me, why would they program it like that?

grenv: not usually done on perpose. It just depends what kind of rounding formula is used on the random table. Most random formulas generate a number between 0 and 1 you then multiply that up to get a number between say 0 and 5. Add 1 and you 1 to 6 but if you round the numbers to the nearest whole number you will get 2 to 5 being more likely and 1 and 6 being not as often.

Subject: Re: Statistics

mctrivia: if the original number (0-1) was random then it wouldn't have that effect, unless 0 and 1 are not possible or something like that.
Would the result be less random than a real dice I wonder?
