# Thread: Is a 1% sample rate in population 25 million suffcient.

1. ## Is a 1% sample rate in population 25 million suffcient.

I have been told by the Office for National Statistics that they calculate the median national wage in the UK using a sample rate of 1%.

Can this truly give an accurate reflection of what the media will, rightly or wrongly, call the average UK wage ?

2. ## Re: Is a 1% sample rate in population 25 million suffcient.

This was quite intriguing so I read up on it. You cannot say how accurate they are without knowing the standard deviation of the wage. Take a look at http://library.lincoln.ac.nz/Global/...ample-size.pdf under the heading "Estimation and Sample Size Determination for Finite Populations" if you want to know how to calculate how accurate a sample of 1% is.

3. ## Re: Is a 1% sample rate in population 25 million suffcient.

I did a bit more research, this article on page 380 suggests that the standard deviation of hourly wage is £2.69 http://www.ucl.ac.uk/~uctpb21/doc/6%20DustPer.pdf

For most applications people take a 95% confidence interval so I'll take the z-score to be 1.96

From the method in my earlier most the required sample size n is $n= \frac{z^2\sigma^2}{z^2\sigma^2+e^2(N-1)}$
To simplify things a bit, since N is several million I will take N-1 to be N
$n= \frac{z^2\sigma^2}{z^2\sigma^2+e^2(N)}$

Since they are taking 1% of the population n= 0.01N

$0.01N= \frac{z^2\sigma^2}{z^2\sigma^2+e^2N}$

Rearranging

$e^2= z^2\sigma^2(\frac{1}{0.01N}-\frac{1}{N})$

$e^2= z^2\sigma^2\frac{99}{N}$

Now for hourly wage $\sigma^2=2.69^2= 7.24$
And the size of the labour force N is approximately 32 million
And $z^2=1.96^2= 3.8416$

Putting those into the equation you get

$e^2= \frac{1835}{32000000}$
e= 0.0076

This shows that they are 95% sure their estimate for average hourly wage will be less than 0.76p (under 1p) different to the true average . Seems very low to me, the error for monthly salary would of course be higher than the hourly salary, then again, 300000 is quite a big sample size

4. ## Re: Is a 1% sample rate in population 25 million suffcient.

Thanks for the effort Shakarri, I do appreciate it, but unfortunately I am none the wiser.

I will rephrase my questions:

is a 1% sample rate large enough to make an accurate median figure?

does it depend on sample size?

We will never be able to get the actual data that the ONS use ( paranoid anal red-tape obfuscational bureaucacy ) so will never be able to assess the s.d. of the wages that they apply, so........

would you risk your life on the accuracy of their 'median UK wage' ?

5. ## Re: Is a 1% sample rate in population 25 million suffcient.

The bottom line is: This shows that they are 95% sure their estimate for average hourly wage will be less than 0.76p (under 1p) different to the true average.
Under 1p is tiny compared to an hourly wage. Lets say we under-estimated the standard deviation of the hourly wage a lot and the standard deviation is actually double what we though. The amount they are off the mean by is double 0.76p, they would be off the mean by 1.52p.
Lets say that these calculations for the mean are not so good at predicting for the median's accuracy and their estimate for the median is worse than we expect, we'll take it as being half as accurate so that they have the median accurate to within 3.04p.
I guess you are interested in a weekly salary, so taking a 40 hour week as being the norm, the inaccuracy of the estimate for median weekly salary would be 40 times 3.04p= £1.22.

So taking the worst case scenario where the assumptions I made in the calculation were under-estimating the error, the government should have a median weekly salary figure that is exact to within £1.22 of the true median. That seems accurate enough to me.

How much does it depend on sample size?
Doubling the sample size will approximately halve the error, tripling the sample size will approximately third the error.

6. ## Re: Is a 1% sample rate in population 25 million suffcient.

Thanks for your continuing effort and explanation Shakarri.

I am going to further push your patience - I totally accept what you say about doubling the standard deviation having so small difference to an hourly never mind a weekly or monthly wage - but would you agree that with such a small sample size, the sample spread would be critical? i.e. a few millionaires making in excess of £480 an hour in relation to those on the 'minimum' wage of around £6 an hour would be highly significant and would you take an actual proportion of those on such a high wage in actual terms to the number not on such a high earnings and incorporate that into the calculation, be it median or 'average' wage ?

-and do you think the ONS ( or any data processor ) would do this?
-and is it an easy statistical method to apply?

7. ## Re: Is a 1% sample rate in population 25 million suffcient.

Remember that the sample standard deviation is independent of population size. If you surveyed 10 people in London out of the 5 million workers and found the standard deviation and then surveyed 10 people in the UK out of the 25 million workers and found the standard deviation they would be equally accurate; just because you surveyed a smaller proportion of the UK than of London does not mean that the estimate you got for the UK is less accurate- the important thing is that you sampled 10 people.
In your example the important thing is you sampled 250000 people. You can look at confidence intervals for the standard deviation to see how close your sample standard deviation is to the true standard deviation. I checked how accurate the standard deviation should be for a sample size of 250000 and it is very nearly exact, because the sample standard deviation is nearly the same as the the true standard deviation the millionaires earning £480 and hour are not distorting the survey.

8. ## Re: Is a 1% sample rate in population 25 million suffcient.

I thank you yet again for trying to enlighten me Shakarri.

I have been pondering your last answer for some time and accept your "Remember that the sample standard deviation is independent of population size. If you surveyed 10 people in London out of the 5 million workers and found the standard deviation and then surveyed 10 people in the UK out of the 25 million workers and found the standard deviation they would be equally accurate; just because you surveyed a smaller proportion of the UK than of London does not mean that the estimate you got for the UK is less accurate- the important thing is that you sampled 10 people. " due to my lack of getting my head around s.d. but accept that they may be both as accurate but not equal.

I still fail to understand in the median wage example how the actual samples used would not be crucial to the outcome median........... but with regard to your "You can look at confidence intervals for the standard deviation to see how close your sample standard deviation is to the true standard deviation." here is an exact copy of the ONS responses I got and does this change your view on the accuracy of the ONS median Scottish wage which was my original enquiry with them referring to this Scottish Government webpage:
Earnings

Dear worthatry

The Annual Survey of Hours and Earnings (ASHE) is based on a 1 per cent sample of employee jobs taken from HM Revenue & Customs (HMRC) PAYE records. Information on earnings and hours is obtained from employers and treated confidentially. ASHE does not cover the self-employed
nor does it cover employees not paid during the reference period. In 2011 information related to the pay period which included 13 April.

Response rate for the 2011 ASHE is based on approximately 190,000 returns. The ASHE samples from the PAYE system, but weights responses to the number of jobs from the Labour Force Survey.

The headline statistics for ASHE are based on the median rather than the mean. The median is the value below which 50 per cent of employees fall. It is ONS's preferred measure of average earnings as it is less affected by a relatively small number of very high earners and the skewed distribution of earnings. It therefore gives a better indication of typical pay than the mean.

Figures for Number of Jobs are for indicative purposes only and should not be considered an accurate estimate of employee job counts. Below is a snapshot from ASHE Table 5 which indicates 1,379,000 paid jobs in Scotland for employees on adult rates who have been in the same job for more than a year earning a median gross average of £25,490.

The attachment should be here

I hope this answers your questions but you will find further information from the Annual Survey of Hours and Earnings Guidance and Methodology section.

Regards

Sarah
