Since I first noticed the small print in TV adverts , that state how big the sample was to get the percentage agree
I am shocked at how few one needs.
Any one else noticed this ,is this a new thing ?
One yesterday was some thing like 70 something percent of 24 people agree !!!
that to me is as near to just sample and sooner or later you will get the results you want,
I'm surprised how bad the sample size is
I started this in general as it was a "rant",
but I'm wondering if it should be in maths ?
Any thought on how to define what a good sample size might be
I'm thinking of raising a complaint to the advertising standards authority that the results are not statistically significant
and they should be to be advertised.
