I hadn't realised that the full sample was 684, so the confidence interval is actually 3.75%.
So, when they say that 70% of respondents believe the board don't have the clubs best interests at heart, then a more accurate thing to say would be:
We can be 95% sure that 66.25% - 73.75% of all West Ham United fans believe the board don't have the clubs best interests at heart. So, best case scenario, 2 in 3 think it, worst case 3 in 4 think it. Either way around, it's not a brilliant set of results for the board, and you can be reasonable confident in it.
And FWIW, a confidence interval of less than 5% and a 95% confidence level is really high, and would be more than enough to make decisions on in my field of work at least.

Alderz, does it make any difference that it's a self selecting sample from a group that was set up specifically because some people were dissatisfied with how the board/ club were running things, and the people who joined are therefore more likely to express dissatisfaction... I mean, it's not a representative sample by any means. Not on attitudes, or any other criteria such as ethnicity or age, which they reported, and probably sex too, although they haven't made those figures public.
Don't your statistical things depend on a uniform sample, like polling samples? Edit- I've just read an interesting guide to interpreting poll data on the British Polling Council site, and I think I would be fairly confident in saying that the poll results shouldn't be seen as representative of the WH fanbase as a whole because the sample is skewed.
Imo, the maths is sound, but, as Mrs G says, there's a danger the sample is skewed. I mean, it's obvious that the only ones thinking G&S are doing what's best for the club are club plants put into the group by G&S to stop the results showing that 100% think they're only looking out for themselves.

Yeah it does. We have no idea about bias in the survey, and you’ve got to consider it but can’t really measure it. I guess what I’d say is that it’s safe to assume the findings are roughly correct, it you should probably whack a few caveats on it.

I think I can say with a degree of certainty that the board will have 0.00% worries about the opinions of 684 fans especially when 71% are some of the 54k season ticket holders who have renewed for next season
The London Stadium is loosing money for the owners and takes a lot of management time. West Ham United (whoever is the owner at the time) will do a nice deal when it’s sold. That is the property deal.

The "owners" are the Greater London Authority, funded by the taxpayers of London (myself included). The stadium is losing about £20m - £30m a year which isn't that much in the scheme of things, by comparison TfL's operating costs are approx. £150m a week and 2018/19 it had an operating deficit of £400m pa (down from £1.5bn in 2016/17)
However the stadium cost £750m to build and convert, selling it for anything less that it cost could be politically damaging for the Mayor.

Says 71% of the responses were from Season Ticket Holders.
According to the sample size calculator I use at work, a sample of 485 gives us a confidence interval of 4.45%, with a 95% degree of confidence.
So, you can be 95% confident that those 485 fans represent all West Ham fans to within 4.45% accuracy.
(Only teasing, you've explained the maths very well, thanks 👏👍)

"[The group] had zero interest in the football side and saw it as a property move. It was a property deal, not a football deal to them."
Such an abhorrent little midget
