First of all well done! I like the topic and I know from experience how laborious gathering statistics can be. I would also like to use the opportunity to elaborate a little on the sample size (the 167 participants) as well. Sample sizeWhen undertaking any sample survey (a collection of information from only part of a population), you may experience what is known in statistics as a “sampling error”. The sampling error can be defined as the difference between the estimate derived from a sample survey and the “true” value that would result if a 100% sample survey (the whole population) were taken under the same conditions.
The sample of 167 people seems (very) small to me. How many programmers are out there? What sample size is necessary to be able to reliably say something about the population?
I welcome your idea to expand the test and put it on O’Reilly.
