[R] Size of observations

[Amit Kabiri]

Hi All

 

I had to assure the randomness of backgammon game's two dices.

 

I took 8,000,000 observations and found that one of the dices is not uniform
distributed.

 

I took 80,000,000 observations and found that the dice is uniform
distributed. 

 

In both tests I used Pearson Chi Square test.

 

My questions:

 

1.      How many observations should I take?
2.      How much the 80,000,000 observations test is batter from the
8,000,000 test?

 

 

Thanks in advance for your help
