How Many Customers For Big Data?
12/30/2017 at 7:34 AM ET
I'm creating an IT Service company which will run on a global level, and we are very interested in using the quantitative and qualitative data our customer behaviour (anonymously) creates for analytic and research purposes.
Now the question I have is, what is the number of customers I have to cross, so the data is really usable? a hundred per country, 10'000 per country? I know there are theoretical numbers floating around, from studies as well as from the academical area, but I don't know them nor find them on the net.
Thanks very much!

Some answers to your question about statistical sample size:

It depends on how you want to analyze the results ... and ultimately what you want to learn and how the results will be used. For example, if you need to look at results by industry sector or IP location, you will need a larger sample than if you only care about "everyone."
In short, start with the objective and let a market research professional determine the right N for your research. It will almost certainly be different for each country, at a minimum.
(Let me know if you need a referral to someone who does this sort of thing.)
