Yes, I believe it is a fact. .... From the top 4 sites and 204 non-exclusive photographers, 93 said iStock gave the highest RPI.
Yes, I read it in the other thread. I'm a methodology freak (probably a handicap left over from a previous job) but with 93 out of 204 = 46%, istock doesn't have the highest RPI for
most, not even for the
majority. Given a margin for a low confidence limit on a sample of just 204, you can safely say that istock gives the highest RPI for
half the respondents.
I always loved statistics and the result raises some interesting questions, for instance the correlation between the reported RPI and portfolio size on every site. But that takes us too far, and the question wasn't in the survey.
good point.. I would say we are getting technical but when talking about numbers and stats I suppose it is important
You would be right, iStock does not have the majority, only the highest % of yes'
We don't have the RPI / vs portfolio size but we do have the vote for the 'best earning site' and in that question shutterstock was a clear winner.
