How do we know that truly random samples accurately represent general populations?
In: Other
With something truly random, there’s no way to know for sure. At least not without taking census and asking everyone.
But the chances of not getting a representation of the general population are very low.
[In fact, there’s a whole sub field of determining just how big the sample should be to get the odds at a particular lowness.](https://en.wikipedia.org/wiki/Sample_size_determination)
