Why Programmers Need To Learn Statistics 572
David Gerard writes "Zed Shaw writes an impassioned plea to programmers: Programmers Need To Learn Statistics Or I Will Kill Them All. Quoting: 'I go insane when I hear programmers talking about statistics like they know s*** when it's clearly obvious they do not. I've been studying it for years and years and still don't think I know anything. ... I have taken a bunch of math classes, studied statistics in grad school, learned the R language, and read tons of books on the subject. Despite all of this I'm not at all confident in my understanding of such a vast topic. What I can do is apply the techniques to common problems I encounter at work. My favorite problem to attack with the statistics wolverine is performance measurement and tuning. All of this leads to a curse since none of my colleagues have any clue about what they don't understand. I'll propose a measurement technique and they'll scoff at it. I try to show them how to properly graph a run chart and they're indignant. I question their metrics and they try to back it up with lame attempts at statistical reasoning. I really can't blame them since they were probably told in college that logic and reason are superior to evidence and observation.'"

Programmers Need To Learn Statistics Or I Will Kill Them All
Okay, two things: First, threatening programmers never work. Management's been trying that for years. Second -- don't you mean 'kill -9' them all, or maybe demalloc(), or cast them to void*, or one of a dozen other witty things you could do besides the mundane answer of threatening stabby bits on them because you have a case of intellectual snobbery?

Don't you think this might be telling you something, like... perhaps statistics are too hard for you? Leave the real work to the people who do know what they are doing and do know something about the field: programmers.

Or are you simply taking something that seems like a data point and extrapolating it to cover a vast swath of applications?
Well yeah, that's what he was saying -- statistics!

Statistics for XXX are uniformly awful, blind leading the blind.
They have statistics for porn? (!!)
What could be wrong with that? And blind on blind action? Strange, but interesting.

Crash course in statistics... The result you got is not 'refined', you get the 'vital' variables like who has a mustache, ugly shirt... things that might be more likely to group people together. Ugly people hang out with ugly people and vice versa, you get the point.
Then you go around asking them to lend you some money, if they don't, their stats go down pretty quick, it's also a plus here if their memory is bad or maybe suffering from early onset alzheimers.
When that's well and done you use a differential algoritm with the other stats and this 'noise' you have gathered to get a nice graph.
And finally you put the values into excel, and make a nice pie chart which you copy paste into Power Point.
Present it to your superiors and tell them how much work you put into it. Also if there is a glitch in the presentation, like odd values or discrepancies, tell them the IT sector screwd up.

"I construct two sets of n=100 random samples from the normal distribution. Now, if I just take the average (mean or median) of these two sets they seem almost the same."
So its true. The n's justifies the means.

No, it doesn’t. If someone spends years and years on a topic, and still has the feeling he understands nothing at all, then clearly, he’s just too dumb for it.

Everyone knows that 98.2% of all statistics are made up on the spot.
From this we can see that 98.2% of that statistic was made up on the spot, meaning only 1.8% of all statistics are really made up on the spot. By repeated application of this we can conclude that either:
