Statistical Thinking
The process of using wide ranging and interacting data to understand processes, problems, and solutions. The opposite of one factor at a time (OFAT), where ones natural born tendency is to change one factor and “see” what happens. Statistical thinking is the tendency to want to understand complete situational understanding over a wide range of data where several control factors may be interacting at once to produce and outcome. Common cause variation becomes your friend and special cause variation your enemy. Attribute judgements of good and bad are replaced with estimates of significance with given confidence.

Economy: Food for thought
To her who was careful on putting her money in the bank, does not take risks, and does not borrow more than she can pay back comfortably — if everyone had this mindset we might have escaped the mess we are at now
To everyone – Now that mindset won’t help us get out of this mess
Why sell ice to eskimos when you can sell life jackets to the drowning man?
Doesn’t that make sense? Yeah, it does.
Why push for customers when you have a different set of customers pushing themselves for the products. Know your market. Digg in.
Exam Fever
You know about exams. I mean who doesn’t. I can’t remember how many exams I have taken till this age. But one thing has never changed. The dread.
I just took the stats exam today and I was all cool just before the start. I have read all the material pretty well and was confident enough to crack even the toughest probability nuts. But see. After exactly 75 minutes later I found myself all wrong. I was splashed by a bucket of freezing water just to remind how wrong I was. Needless to say I screwed up the exam.
So what’s the catch? Are exams always meant to be that way? Well one good thing about all these repetitive experiences is that, they warn you of your complacency. In a sense they will always charge you up with the feeling of insecurity or feeling of being a beginner again. That reminds you of facing the unexpected, facing the chaos or broadly facing the real world.
And you know the best thing about exam? No matter how much you screw up the last one, they always keep on coming. I better catch it next time.
