Trekka,
I am not particularly interested in splitting the results by football club. But I am interested in knowing which approaches are working in terms of people taking up the trial. I guess the blues fans were more up for taking it all at face value as they know me as a poster on the forum.
I would like to get a broad range of the population trying the tests, and football suporters are quite good in that respect. Football cuts across many boundaries (age, class, job, income) providing diversity in the sample, but it is not so good in other respects (i.e. mostly blokes from Brum).
It is hard to find enough people to do the trials, so I am trying to extend the sample as best I can. People are taking the test in uncontrolled conditions, and they may not try, or they may take the same test several times to try to get a high score. I can, to a large extent, identify through statistical analysis the people who are less serious - but you are right, it is a problem with the research data and it is not ideal.
People can do the tests without giving any information, but they can't be entered for the draw if they don't. If you put your name as 'Trekka' or 'Paul Lambert', then if you won, we would email you saying..."Congratulations Trekka (or Paul Lambert)...." ... to whatever email you put down, so really, you don't need to give your name.
Go on... have a try.
