Car driving test data by test centre theory based test scores by ethnicity for 2017-18

John Fuerst made this Freedom of Information request to Driver and Vehicle Standards Agency

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was successful.

Dear Driver and Vehicle Standards Agency,

I read with interest you reports :​

"Car driving test data by test centre Statistics about car driving tests, showing pass rates for each driving test centre by gender and ethnicity, and first-time passes."​

To better understand the cause of the pass rate differences by ethnicity -- and, specifically, possible adverse impact owing to the multiple-choice tests, I would like to request the ​
theory-based multiple-choice test scores for the 2017-18 year. Specifically, if possible, I would like the sample sizes, average scores, and standard deviations by ethnic group (based on all data across test centres) for the year. ​

Yours faithfully,

John Fuerst

Dear [email address],

Thank you for the information. What you provided is what I was looking for. However, could you provide the means and standard deviations with two significant figures; i.e., two numbers to the right of the decimal point, such as 4.12, instead of 4.

Yours sincerely,

John Fuerst

Dear [email address],

Thank you so much for the updated Annex. However, could you show two decimal points for the ethnic group means and standard deviations, as requested? Instead, you have just added them for the percentages.

Yours sincerely,

John Fuerst

Dear [email address],

I am writing to prompt you to reply to my follow up request:
https://www.whatdotheyknow.com/request/c...

Earlier, I had requested you to show two decimal points for the ethnic group means and standard deviations. However, in reply, you added them for the percentages only.

Might you provide the means and standard deviations with two decimal points, also? Thank you for the help.

Yours sincerely,

John Fuerst

Dear [email address],

I have asked repeatedly for the raw test score MEANS and STANDARD DEVIATIONS to the NEAREST HUNDREDTH PLACE (i.e., with TWO DECIMAL PLACES). That allows for more precise calculations of group differences.

Can you please let me know if you can do this?

I do appreciate the time and effort.

Yours sincerely,

John Fuerst

Dear Mr Fuerst
 
Thank you for your further email.
 
I have contact the subject matter experts who provided the original data
that you requested, and they have advised the following:
 
The sample size of the data has been provided in the column headed
Container Graded
The standard deviation has been provided in the column headed Container
Raw Score StDev
The average score has been provided in the column headed Container Raw
Score Mean
 
This information matches the request that you originally sent on 13
January.
 
I apologise for any confusion and I trust that this has helped to clarify
the issue.
 
Yours sincerely

Dear [email address],

On January 31, I updated the request, writing:

"Thank you for the information. What you provided is what I was looking for. However, could you provide the means and standard deviations with two significant figures; i.e., two numbers to the right of the decimal point, such as 4.12, instead of 4."

Can you let me know if you can provide the mean scores and standard deviations with two significant digits? In the original response you provided them rounded to whole numbers.

I understand which numbers are means and which are standard deviations. That is not the problem. What I want to know is if I can get more precise information, specifically, the means and standard deviations to two decimal places. Please let me know if that is possible.

Yours sincerely,

John Fuerst
