What you're doing IS statistical analysis, just not ridiculously complex analytical techniques. And in the real world, "this many people think this, out of this many" is often more useful than the standard deviation or fit-to-weibull-distribution
Firefox. oddly, I had to install Google Chrome on my Dad's PC because it was the only browser that would run games from his favorite website- Pogo. but i still prefer Firefox.
when it comes to statistics Ill give you one advice. always be critical against it. Its very easy to make the result you want. But that is another thing. and if you go in with the attitued that you suck at math then your not tryign hard enough. Baisic math can everyone learn. good luck.
At the moment I am using chrome but I prefer firefox. When I tried out firefox 4 I fell in love with it but after a while it started to do crazy thing, so I stopped using it and went back to Chrome again.
I've generally used older Flock & Netscape variants, but they fall into the Firefox group so that's my pick. Opera is cool too, so if you get too many people saying "other", you could look into asking about this one as well. IE is the worst browser in the history of cybertron, and Google Chrome is just too hip for my heart.
