For your information, I’ve taken a number of college courses on statistics – including Research Methodology just last semester – so I do know that the accuracy of any data sampling is largely dependant on the percentages involved. In any data collection the number of individuals studied is completely meaningless without knowing the size of the overall population that makes up the study group. The same is true for the time periods involved, and for anything else that might be a factor in a study (like weather, and time of day).
The data collected is not considered viable unless it can be determined that it accurately represent the entire study group. And studies of this type are not even considered viable when members of the test population know about the study and the location of the study areas.
You and others here try to use the report as magical proof that speed is not an issude. Do you expect anyone to believe that this study accurately determined the boat speeds on the entire lake over the entire summer? There just wasn't enough data collected to make the study viable (since only portions of the lake were covered, and data was collected during less than 2% of the daytime boating season).
On top of that, the fact that radar was being used on the lake last summer was well published - along with the location of the study areas. No traffic study is ever considered viable when the public is aware that it is taking place.
The report does not even give the statistical analysis of the data collected – if it had, then the percentages would have been factored into the analysis, and the degree of accuracy of the study would have been given.
This is a quote, taken directly from the report: While emphasis was placed on weekend boating activity, data was also collected on weekdays. Just because data was collected on more weekdays, does not mean that more time was spent collecting data on weekdays. You would need the log with the hours per day that data was being collected to determine that.
How much data was collected out on the Broads?

The study proves that you could not have possibly had as many "close calls" with speeding boats as you allude. Especially when you consider how few times you have been on the lake. What more could you possibly need to know about the population of the study that would be relevant? In any study, capturing 2% is a pretty good sample, if we accept the premise that hours of daylight is important, which it isn't.........
As far as the accuracy of the study, even though I don't think it is true, let's suppose they missed 50% of the boats that were above 45, that would bump the total from 0.9% to 1.8%, still a very small number, so what?????
You keep bombarding us with inaccurate info. only 2 out of 9 areas were published, so you are wrong again. Wrong, wrong, wrong.
Common sense, a speed limt isn't going to help you. The only thing that will make you feel safe is a power boat ban, and that isn't going to happen. The world doesn't revolve around you. You should have learned this by now.
Show me some data that supports a speed limit, you have none. Just a group of people using scare tactics. Tactics that have been exposed and pretty much admitted or shown as being untrue. When you see some actual data, you try to torpedo that, but you are foiled again....
