They only asked 1,000 adults via phone calls? Pretty small survey but I’m not a statistician.
Edit: Downvoters. Please comment. Was the survey larger? Is 1,000 a large enough sample size to make conclusions about the whole US? This is HN please engage.
- IncRnd 8y agoThere also is low quality of respondents in addition to low quantity. I don't really think that 15 is adult...

- tlb 8y ago1000 gets you down to 3% margin of sampling error. Asking the question in different ways can affect the results a lot more.
- wil421 8y agoNot very knowledgeable of margin of errors but does 1,000 people, not women, really give you enough data to represent 30+ million females between 15-30?
- tlb 8y agoOut of 1000 adults, you'd expect 125 to be women 15-30. That gives a margin of error for that subgroup of 9% (at 95% confidence level). They quoted 40%, so it's 95% likely to be between 31% and 49%. The size of the population doesn't affect the accuracy of a survey, only the size of the survey.
