Hi,
I have the following headings:
- practice size : let's say 7,800
- respondents : let's say 13
- people who would recommend a service: 11 - meaning 85%
- people who wouldn't recommend a service: 0
- people who said neither: 2
How do I adjust my percentages (85%) such that they reflect the practice size? (each practice has a different size).
Thank you
Hi and welcome to the forum,
How does the practice size change the % of respondents who would recommend? i.e.
What % would you expect for two practices, one with 7800 and the other with 3900, both with 85% of their own respondents recommending?

I'm not clear what results you are expecting to see...
By taking a percentage, you have normalised the result: based on responses obtained: 85/100 people are happy and contented. What would you expect to see, in addition to that??

Hi Glenn,
Perhaps my question should have related to the graphical representation of this- how we can represent the data in order to also take into account different sizes of each practice (rather than a simple boxplot showing the 85% etc.) ? After doing a bit of research it seems a funnel plot would be the best way? Can you advise on the steps to do that with this type of data and how to interpret it best? thank you
If a funnel plot is your preferred method of presentation then check out this site which explains the steps you need to take.
