Wait, what? Surely they should all be (sans a bit of noise) the same? (Split 1000 random numbers into two groups. The sums should be almost equal).
- unionpivo 5y agono if you take big enough group it will average out. But random numbers can and do have "random distribution" which means some high some low, most somewhere in between. But that only works with large enough sample. With small sample size, randomness can look like not random.
