What kind of math is this?

I recognize mean, median and mode, but not the rest...

(X - X) / n

= 0.01

It's Statistics.

It's Statistics.

More specifically, it's "Quantitative Techniques in Geography"

Any recommendation on a good book to get ready for Statistics?

Frankenstein, by Mary Shelley, will give you a head-start.

although i've never used this book, it looks like an acceptable text in introductory statistics. my roommate used it and passed the class with a b even though he was wasted throughout the quarter. i would go ahead and buy the 3rd edition used as it is cheap!

Sigma, slash, parentheses x minus x divided by the size number of the sample

Infinity equals 0.01, which can be is p (probability) > or < than .01 scale

I hate stats

... I am never going to look at a sigma the same way now. Thanks for that.

Well, I was a stats major in undergrad. I know my spiders.

It's not an infinity symbol; it's the greek letter alpha which is used in statistics to denote the confidence interval (or the probably of Type I error) occurring in testing hypothesis.

Stats is usually a painful course, but if taught well it will be extremely revealing. I took a look at some of the sample pages from the other poster's link to that book offered on Amazon, that may be a useful start.

It's also something that _will_ be useful, at some point, in any tech or business career.
