Sociology / Unit 2 Soc 0160 short lesson, about 20 seconds
"A Bigger Sample Is a Better Sample"
Captions available
The idea
Sample size cannot repair a biased sample: how members were selected governs whether a finding generalizes, and no quantity of the wrong people fixes it.
In practice
A magazine poll of two million of its own readers describes its readers, not a country.
Where people slip
Large biased samples are more persuasive and no more correct.
