Eurobowl Dice: loaded or not?
Posted: Tue Nov 10, 2009 11:45 am
Hello,
On Sunday evening I was playing a game versus Old Magic Tobe, when Geoff pointed out to me that the Eurobowl dice were loaded. I was actually a bit amazed about it. Because to me the dice are an especially nice souvenir and I'd like to use them in the future, so I decided to do a little test to see if they are indeed loaded. This to make sure I'm not going to get accused of using loaded dice just because I like those dice.
In short, 1000 dice rolls later this is what I threw:
1: 16,6 %
2: 17,8 %
3: 17,2 %
4: 18,0 %
5: 15.2 %
6: 15.2 %
Doing a bit of statistics, I also checked if the values 5 and 6 were especially off the mark, making the dice roll lower, but everything should be within acceptable bounderies for a normal dice distribution, as only 1000 rolls were done.
In short, even though the 5's & 6's do come out lower in the test and 4's & 2's comes out higher, the distribution is well within statistic bounderies.
To me this is good news as it means I'll be using these from now on, and nobody will be not using them because they 're "loaded".
For those interested, on a 2d6 roll these are the chances to roll if the given values are completely correct (which as above stated they're not because the sample was too limited):
2: 2.76 % vs 2.77 % ideally
3: 5.90 % vs 5.55 % ideally
4: 8.88 % vs 8.33 % ideally
5: 12.10 % vs 11.11 % ideally
6: 14.40 % vs 13.89 % ideally
7: 16.64 % vs 16.67 % ideally
8: 13.88 % vs 13.89 % ideally
9: 10.70 % vs 11.11 % ideally
10: 7.78 % vs 8.33 % ideally
11: 4.62 % vs 5.55 % ideally
12: 2.31 % vs 2.77% ideally
I'd say they are save to use and the deviation of the values is within bounderies to use them savely without being accused of using loaded dice.
Important remark: the fact that both 5's and 6's are lower should not put you off. The reason for this is simply that I threw less 5's and 6's than statistically would be the average.
