This is barely a rant, more of an observation.
Why on telly adverts do vendors get away with saying 71% of 65 people, Then the next is 56% of 4445 people?
Would it not be a fairer reflection of what a cross section looked like if they all had to use the same number, say 1000.
100% of us 2 think this.
Ooh, we're nearly rantin' and it be Thursday!

Saw one the other day that said "82% of 29" !!! 
That was of course probably the advertising team as it was raining outside and they didn't want to ask the public for fear of getting they're hair wet! |

"Would it change the percentage though?
Yes it would, this is why I have a disliking for marketing ppl. They always find a way to cloud ppls judgement with their hazy stats. X"
im really crap at maths! Off to test this theory! |

This will haunt me in all my days. When i was doing my A level socialogy extended essay i deviced a questionaire and circulated it to 50 people.
Then i plotted it all out and wrote my paper on the results.
The one fucking thing i forgot to write was how many people i interviewed. My mark was knocked down to 94% and was told i would of got 100% if i had put that information in |

So long as they use a percentage then the comparisons are fair.
As for the sample size; it's only honest to use the number of people who agree to answer the question so some samples will be smaller than others. |

Personally think that the ASA should ban all claims on surveys involving fewer than 1000 people.
With such small samples you're going to run into a potential huge bias for any product.

Maybe you stop asking the questions when the percentage in favour of your product starts to fall.
Lies, damned lies and statistics.
If you had a set number you had to ask, this would stop these tiny sample groups. |

This is exactly why they use the odd numbers for sample size so you cannot quickly work it out. The percentage with those figures always sound better than one you can work out quick. |

Any scientific study must by law be based on a minimum of 1000 people.
For these ads what the do is survey many small groups and then pic the best result....so they survey 65 and get 72%, then 84 and get 68%, and so on.....sometimes the survey group is ridiculously small because that gave the best percentage result. Basically as with all marketing its spin. |
