Sample sizes; always sample sizes. Of course the demographic composition may be less than generalized...but are said to be politically "central".
Yesterday’s Mindtracker for PMQs was very interesting datawise for political geeks, over a thousand people (1,150 people between 4 p.m. and 10 p.m.) twiddled their knobs online, so the poll is statistically valid. In comparison Frank Luntz typically has only 30 people polled in a room. Watch the video above to see how people responded in realtime.
