And that causes the problem that the parent describes: greater variability makes it harder to find useful patterns.

- wesleywt 5y agoA dataset with no variability makes it impossible to find any useful pattern. You are only counting the blue M&Ms in the jar. > Europeans are not clones In terms of genetic diversity, yes, they are. I don't know where you get your opinion from, but in science, the more representitive the scientific sample of the population is better the statistical analysis of that population. A European/Asian only dataset it not representative of the actual human genetic diversity.

- float4 5y agoAccidentally removed my comment when I wanted to reply, but whatever. I never said that we can infer everything from European data. I never said collecting African genetic data is pointless. I know that Europeans do not vary nearly as much from a genetic standpoint as Africans (although they're definitely not clones). I know you can't generalise using European/Asian data. I know larger samples describe the population better. All I said is that it's easier to analyse data that is less variable, and that Europeans aren't clones. Both points are true. Finding patterns is more difficult when there is more variance in the data. That doesn't mean it's pointless, it's actually more useful, but it's also more difficult.
