# How important would a statistics course be to a software developer?

How important would a statistics course be to a software developer? More specifically given the description:

2510 Statistics for Physical Science Students (F) & (W) examines elements of probability, conditional probability, Bayes' Theorem, discrete random variables, cumulative distribution function, introduction to continuous random variables, mathematical expectation, estimation of mean, proportion and variance, hypothesis testing for one-sample case

I'm trying to find out whether I have room to add more CS courses. This course (STAT 2510) is not required, but is "recommended".

This question came from our site for professional and enthusiast programmers.

More important than you might initially expect it to be. Probability and the ability to impose certain types of distributions on an input can help analyze certain algorithms, and in some cases improve their performance (see Quicksort). There is also the stat under-pinnings of hashing. I wouldn't say it is critical as you can probably pick up most of the statistics knowledge you will need from any good algorithms book (CLRS for example) but it is useful.

Forget about whether this is useful to a programmer. I find this basic statistics knowledge so indispensable that I don't understand why it's not taught in dumbed-down form (i.e. without calculus) in high school. Learning these concepts can be useful in data mining/machine learning fields, since this field is arguably the intersection of statistics and computer science. Even if you never do any data mining, understanding basic statistical concepts will make it easier for you to interpret things like performance benchmarks. It could even be useful for understanding things like Web server load. The number of users signed on can be modeled as a random variable with a Poisson distribution, though the Poisson parameter may vary by time of day.

Disclaimer: I work in bioinformatics, which is basically the intersection between molecular biology, statistics and computer science, so of course I like statistics and think it's important.

+1 Basic statistical analysis is an indispensable skill. –  dietbuddha Apr 10 '11 at 23:21

I suppose I'll take the course then! In an unrelated note, I agree that more math should be taught in high school. In fact, I think that all students should complete Calculus AB and BC before graduating high school.

Unfortunately I screwed around too much and didn't take these in high school myself. My Calculus I final is Thursday!

Probably better as a comment than a post –  Wayne Werner Apr 10 '11 at 22:44
My apologies, I'm still getting used to StackExchange. –  user22635 Apr 10 '11 at 22:55
I'm sure most of us have at one point or another. But now you know ;) –  Wayne Werner Apr 10 '11 at 22:57

It depends on what kind of software you will be developing. I didn't take a statistics course and I know plenty of good developers that didn't and we're doing just fine without it.

My advice would be to take whatever course you find more interesting.

its probably one of the more useful branches of math for a general software developer

So would you recommend taking this course over say a course on complexity or computational intelligence? I'll be taking an AI course and I have considered going to grad school and studying AI further. –  Ti-Tw Apr 10 '11 at 21:35
There are more jobs for programmers who know stats than for programmers who know AI. –  quant_dev Apr 10 '11 at 22:05
@Keith Could you explain why? –  Ubiquité Apr 10 '11 at 22:14
