<p>Responses from people passing a point are biased towards people passing that point and not all other points.</p>
<p>We know that many, perhaps most, of the residents of Harringay are not members of HOL and may not have access to social media. So the sampling is biased towards a particular population which is not representative of the whole.</p>

As I explained, that is not random sampling. Sampling mainly from a small number of streets is most definitely not random, and sampling people passing a point, or via a link introduces a level of bias. There is also no attempt to make the sample representative.<br />
<br />
A valid sample would have been representative of the area by characteristics, and also truly random (ie involving a random number generator to survey certain addresses).<br />

<p>The map with shaded areas indicating traffic management around the borough is hilarious.</p>
<p>The whole of Finsbury Park is traffic managed? The railway line along Wightman Road? In Stroud Green the whole area North from Oakfield road is shaded except Denton Road, when actually all these roads are open to through traffic (Mayfield Road, Inderwick Road, Uplands road etc.)</p>
<p>The Arena retail park?</p>

But the bulk of the respondents were randomly sampled. The table shows those those roads where they had been door knocked end to end but most of the responses came from either people passing a point (Harringay station for instance) or people who responded to a link taking them to an online version of the questionnaire. That's how a sample size of almost 1,000 was achieved.

Suppose I wished to survey a school (year 7-11) and wished to find out if they liked school dinners. I have done calculations and have found that 50 is a statistically significant sample size.<br></br>

Suppose I wished to survey a school (year 7-11) and wished to find out if they liked school dinners. I have done calculations and have found that 50 is a statistically significant sample size.<br/>
<br/>
I then ask the first 50 year 7s in the lunch queue, 'Do you like school dinners?', and 80% reply yes. I cannot then conclude that the majority of the school likes school dinners as I have not made the sample representative (by school year, but also by other characteristics such as gender). I have also not selected by sample randomly, to the contrary, it is what is known as a biased sample, as the first children in the queue are more likely to like school dinners.<br/>
<br/>
The sample taken by 'Living Whightman' is not representative of the ward. To do so, the sample would need to representative of the area in terms of geography, and other characteristics such as car ownership. There has also not been any random sampling.<br/>
<br/>
Therefore, this study is flawed, and it would be absolutely false to conclude that the majority of the ward is in favour of Whightman road closure. We cannot even conclude that the majority of Whightman road/ladder residents are in favour of the closure, due to the manner in which this study has been conducted.<br/>

The bus times were supplied by TfL and do include rush hour. The sample size is statistically valid. If you look at some earlier posts in this thread the confidence interval for a sample of this size is discussed at some length.

I have read the entire document, and have taken from it that Whightman road residents indeed have a lot of time on their hands. This document is however rather meaningless, and it would be a travesty if any changes were made on the basis of it.<br />

4% of the ward population was surveyed, which is being talked about as 'statistically significant'. This is clearly absolute nonsense, as this is in no way a representative sample, and no effort was made to make it so.<br />

<br />
There is no sources for the majority of the data. For example, where does the bus time data come from? Why has rush hour journey times not been included. Certainly, anecdotally I have noticed a much increased journey time.<br />
<br />
I could go on pointing out the flaws, but I don't have time to reference all of them.<br />
<br />
In short, this document is meaningless, and just an illustration of NIMBY'ism at its best. It would have been helpful if those who had compiled it had at least read about basic statistics before creating it.
