It wasn't just the small sample size. It's also the fact that it's a
non-random, self-selected and entirely unrepresentative sample.
For example, if you wanted to determine the average height of adults
in the USA, and survey 3000 current or former NBA players, that would
be a large sample size. However, it would fail the other part, namely
being non-random, entirely unrepresentative of the entire population
of adults, etc.
The combination of both defects in the INTA study (small sample size,
and also non-random) makes the study essentially worthless for saying
anything about the larger population it purports to represent.
Lori talked about "Everything we do is a learning." The only learning
that will happen tonight, unfortunately, is a lesson in how not to a
proper survey. That might be of some value, in helping to design the
future surveys (e.g. making them much shorter, to encourage greater
number of responses; doing proper randomization, like the other study
I mentioned in my first email of this thread, investing more money,
etc.). Nielsen obviously knows how to do things right -- they're a
highly respectable organization. Unfortunately in this instance, what
they produced can't withstand scrutiny.
