You're talking apples and oranges.
First, a correctly done scientific survey has controls in the way that the
questions are asked, so that the do not skew the data one way or the other;
they are often numerically weighted (on a scale of one to four, how do you feel
about a, b or c?), and there is a statistical range of error depending on the
size of the sample universe.
The more people, the smaller the possibility of error; the fewer the people,
the larger the possibility of error.
Asking your buddies down the hall, in an uncontrolled survey, with lots of
variables, isn't a valid survey by any stretch of the imagination.
