edward said:It has been suggested by several that polls are not accurate enough to rely on for information. But let's face it, we depend on polls to gather information about every thing that involves the public and how they feel. For instance even marketing companies use polls extensively. Obviously polls are not always totally accurate, but they are seldom totally wrong.
I would argue that polls seen in the media about "public opinions" are ALWAYS wrong. The fact is that there are way too many variables left unchecked when any of these polls are taken. Variables such as:
Day of the week
Time of day
Questions asked
Specific wording and context
Specific demographics sectioned
Who asked the questions and how they identified themselves
Voice characteristics of the questioner(s)
.
.
.
The list can obviously go on and on. The fact that marketing companies use polls is not a very good argument for polls in the media either, the intended use of the polls and the way they are presented and carried out are totally different.
The fact is that any poll from a previous time can't legitimately be compared to any other poll, unless it is carried out in the EXACT same manner on the EXACT SAME people, other wise we are just trying to compare two completely different measurments of different things.
