After reading a lot of posts patronising Numb3rs I decided to have a taster. Regretfully in Spain was a total disaster (where’s our education system going?), and in Brazil, where I’m currently living, I think it’s on cable (however, from the last news appeared on press, the education system for maths is as bad as an 8th grader, about 14 years old, having problems calculating percentages). Well, but that’s not the point; the thing is I bought the First Season DVD Set and watched the first two chapters. Here we go!.
Minuses:
_ The acting is not very good…, I imagine… yet. It’s just the first two.
_ Why the mathematician has to be presented as a troubled mind?.
Pluses:
_ I liked the way maths is inserted into the action…, natural, we do use maths everyday and this is shown.
_ The most I liked was the way they try to introduce “humanity” within maths. I think our colleagues from INFORMS Section, Behavioral Process Management, will be happy.
Thanks! And remember, It’s just my opinion.

Time and again I’m thinking of the errors people commit; yes, commit, not make, I explain you the reason for my assertion.
In statistics, when we have a declared statement (“null hypothesis” we say) we have two options, haven’t we?: to accept, or to reject (actually, we could rephrase and say that rejecting is accepting the “alternative hypothesis”). So, now that comes the shocking info for those alien to statistics: when we make such a decision we are not just exposed to the error of being wrong or right, we are exposed to TWO ERRORS (brilliant, as if life wasn’t hard enough!).
First error (the “common one”) is what we would commit if our decision is to reject the declared statement when this one is right (bollocks!). It’s what we represent with an α and we’d call it “level of significance” (probability of cocking up failing to accept the right statement); usually statisticians play with levels of 5% or 1%, what means the “confidence level” (1-α) is between 95% and 99% (remember, that’s just probability!).
Second error (the “not-so-known-one”) is called “false negative” (β for friends and colleagues), and is committed when we accept the statement and what was right was the alternative one (again, damned!).
And know here comes the trick. Trying to avoid one (or reducing the probability of committing it) would increase your chances of committing the other (so, another Catch 22 in life). So, the only thing that rests us is to use the best of our knowledge and try to control one without exposing us too much to the other (that’s what statistics are for, mate!). Because, my dear colleagues, avoiding the decision, IS NOT A CHANCE!!!.

Some would say unifying systems is the best option. I’m going to trust them and start combining my messy presence in the web (site, blog, networking…).
Wait for us in the domain kProductivity.com.
See u!
