I know that interviewers usualy have you do math and puzzles when your interviewing for a programming position. I have the book 'puzzles for programmers' to keep me sharp on logic puzzles but I havent done math in a while. What type of problems do they usualy have you do on an interview for entery level position were the postion may have you use a random programming language that is not specified at the time. I need to get brushed up quick but i need to know what to be focusing on.

I haven't had that experience, but I would definitely want you to be comfortable with algebraic manipulations, especially solving for different variables.

For a position that may involve heavier math, such as stats, implementations of mean, standard deviation, etc, would all be fair game.

ok thanks wp. I can solve for most veriables easily enouph, I will have to look up all the formulas thou, i have forgot just about all of them. I can find the mean but when you say implimintation of mean are you talking about finding other values based on a given mean? that might give me some trouble so i will have to hit that hard. Theres not really much hope of me getting stats down and i never even heard of the other one. This should be a fun week at work, doing math while pretending to check fire risers, wew.

Example:

Given a set of data, can you (quickly) write a program that will calculate the mean, median, mode, standard deviation (population or sample), variance (population or sample), and range?
