Political polls and probability

  • who are you polling - is the media picking certain people or accidently missing some
  • misinterpreting what the data are telling you
  • the highest probability of an outcome doesn’t mean that this will happen

Flip 10 times - this is one sample - count the number of heads Repeat 4 times

  • who is in the sample and how big is it?
  • results more consistent with large sample sizes
