The Radio 4 website is running an intriguing survey which asks what the respondent thinks that people in a variety of occupations actually earn, & what the respondent thinks they should earn. What particularly marks it out from any other that I (not a regular seeker out of on-line surveys) have seen is that you can then view the results immediately, expressed in some very simple but effective & easy to understand graphics. It is going to be interesting to hear the programme which discusses the results.
On a more nerdy note, I hope someone is taking regular snapshots of the histograms of the responses as they accumulate – it would be fascinating to see how they evolved as N got bigger. Do they tend towards the normal, or something else?
