Since it's nigh on impossible to produce accurate figures of operating system usage, we have to make do with figures that provide a rough estimate, at best. One such set of statistics are the figures from Net Applications, which tracks the 160 million monthly visitors to its hosted websites. The latest figures from January 2009 have been published, and they show that the rise of Mac OS X continues, as well as that of the iPhone and iPod Touch. Unsurprisingly, Windows 7 did quite well too.

Only if it is truly random, in which case it would be ok. Its the randomness that is critical, raising the numbers will not help if it is non-random.
Non random sample reports are amusing starts to a conversation, but they are not data.

Yes but 160 means some fuuny things:
And HOW FreeBSD came up with 0.01. One Free BSD user come up there and generated those nubers. Maybe there is one lucky FreeBSD user in entire world?
I had statistic (biometrics) lectures in university and based on them I can say that these numbers mean NOTHING.

The sample size is also important. If your sample size is too small, you won't be able to get a meaningful P value, and this means you cannot determine whether the change is statistically significant.

That's supposed to be 160 millions visitors ;-)
At first, I was surprised to read that too : who would care about statistics for 160 users per month?? ;-)

And from where you decided that there is 160 000 000 users questioned? Just added some 0?

The ones who want fake results for their speculations. With 160 you can make "catastrophic" 10% change in month from 3-4 people opinions/actions. and if you do not like results you can repeat same with other 160 and get other results.

is that 160 monthly visitors the correct sample size and not a typo? Because if it is correct, 160 is not an adequate sample size for something like this.
