Things My Wife and I Talk About: Margin of Error
Beautiful Wife: Shawn, on BabyCenter.com, our baby name poll has:
- 6 votes for “Coney Atoll”
- 5 votes for “Viper McStab”
- 8 votes for “Rambo Brite”
- 9 votes for “Dinosaurus Rex”
Shawn: So, the error on those are something like ± 20% (I was being nice, 95% confidence @ 1/sqrt(n))
BWife: … What?
Shawn: Well, you’re only getting a sample of the total BabyCenter.com community, so like, there’s an error because those 28 people only sort of know what the whole group might actually think about our names.
BWife: So you don’t want to talk about this then.
Shawn: … I thought I was helping.
