84%? What's wrong with the rest 16%? Why spend $500+ on something you don't even need, and be unhappy with it?

Not everybody is born with equal intelligence.

And if somebody is unhappy with whatever they bought, then they should sell it. Second hand iPads fetch a decent price and are real easy to get rid of.

Assuming a sample size of 52 (the number of people surveyed), random selection, and a hypothetical population of 10M users, the margin for error is +/- 14%.

You need a sample size of about 1,100 respondents to get a margin of +/- 3%.

If you "added 3 zeros" to the sample size you may or may not get different results, but you would get a much smaller margin of error. You wouldn't, though, need a sample anywhere near as large as 52,000 to get that outcome.

Even with a margin of error of +/- 14%, that means that anywhere from 70% - 98% of all iPad users are satisfied.

I agree that a bigger sampling size than 52 would be useful, but even the big outlets like Gallup usually don't poll more than 1000 people, as it wouldn't be very cost effective, since a +/- 3% margin is good enough.

Also, the margins can and have been proven. You can count out populations of M&Ms, colored beans, etc., draw them out randomly, and hit the margin of error for the measured populations more than 90% of the time.

Only 90% of the time??!!

So there is a chance that I could poll 52,000 people and get a margin of error of ±3%...

Of those 80 apps, how many are paid? I have 100's of apps downloaded but only a handful are paid apps. Plus side for me, many free apps satisfy what I need downside for developers, I do not buy many apps.

52 humans is way too many. I just need one for example - me. Last time i checked i was very satisfied.

We can go through with all the mambo jambo, but it doesn't take a genius to figure that people like their iPads.

21 percent use their iPad in the bathroom. Now that is suspect and probably a joke answer.

Still, if the survey is ±3%, it does bode well for the iPad. I may get the iPad 3 when it comes out, though the MBA 13 would be more practical, possibly.

I just might be in the bathroom right now responding to this post????

The survey found that 83.65 percent of respondents were satisfied with the iPad, while 62 percent ranked Apple's device as "excellent," 10 percent said "best imaginable," and 21 percent said "good."

I think the survey tells us what we already knew - that most people are very happy with their iPads. I can tell that by watching people I know use them.

I think the statistical discussion was a bit misguided. For each of the statistics there is an unkown true value and a calculated value, which is published here. The question is 'how near to the true value is the calculated value?' and statistics enables us to make statements like 'there is a 95% chance that the calculated value is within 5% of the unknown true value' or 'there is a 60% chance that it is within 3% of the true value'. We are dealing with a Gaussian distribution of calculated values around the unknown true value, and the Gaussian distribution goes off to infinity, so there is a small chance that the sample error is greater. Saying it is 'within ± 3%' is just too simplistic. Is that with 95% confidence or 60% confidence? Of course the larger the sample size the better the chance of making more accurate estimates.

I understand the high satisfaction rating, but the percent of users with more than 80 apps seems low. How does one NOT end up with at least 80 apps on an iPad? If you asked me before I read this post, I'd have guessed that I had maybe 40 apps on my iPad. I actually have 124, and I'm not a heavy user of my iPad at all.

I wonder how many apps the average iPhone owner has on their iPhone?

EDIT: oh sheesh. I missed the fact that they barely even had 50 respondents in this poll. That's nowhere near enough to get an accurate measurement. Talk about a tiny sample!

62% excellent + 10% best imaginable + 21% good = 93%, not 83.65%.

Have the statisticians ever been way off course?
