U.S. mobile users sent an average of 357 texts per month in the second quarter of 2008 versus an average of 204 calls, the report said.
The average person sends ~ 10 text messages and makes 7 calls a day?
Wow, I'm behind the curve ...
- dododo 16y agothe mean isn't a robust statistic. i don't think your inference is correct in this case. a single user can theoretically throw the mean off from the central tendency completely. i would imagine there are a few users that send a lot more text messages and calling more than most people, biasing the result. it would be more useful to talk about the median in this case, i think. http://en.wikipedia.org/wiki/Robust_statistics#Examples_of_robust_and_non-robust_statistics http://en.wikipedia.org/wiki/Robust_statistics#Examples_of_r...
- kenjackson 16y agoAgreed. I know many ppl who send 1000 or more texts per month. But I don't think there exist many in the world who make that many calls for personal use.
