lol, they studied 4,000 people. do you have any idea how many people use iPhones? i'll give you a hint, it's a lot more than 4,000. what a ridiculous "study"



Political pollsters question less than 0.001% of all voters in each election cycle, yet their predictions are right more than 90% of the time.

Very small samples can yield very good results when done properly.

If done improperly, even large samples are useless. If they had sampled 1.2 million iPhone users, but only 15 of the responders were Verizon customers- the data would be useless even though the sample size was huge.

Try taking an elementary statistics class before saying stupid things like that.
