Yes, I don't know the maths but this study surveyed 2,000 people from a pool of around 54 million (18% of Britain's 66 million people are under 16 [1]). I don't think those numbers qualify as being enough people within a population of a certain size to avoid unintentional bias.

- reaperducer 7y ago2,000 might actually be oversampling for 66,000,000 people. When the United States had about 300,000,000 people the number for statistical veracity was around 975. Again, my statistics classes were a long time ago, so the numbers I remember are inexact. But once I groked the math, it was surprising how few people you needed to interview.
- cookie_monsta 7y agoYes, there is a comment further down about how population size doesn't matter, that all you need is a sample size of around 1,000. Fascinating. I stand corrected.
