Never mind three more years – some people think just one might be a tall order.
Collecting the data comes first, but then you have to analyze the data.
Any field that collects and analyzes data relies on statistical techniques to make sense of it all. Modern, more accurate methods should supplant the old ways... but in many cases, they haven't yet.
Will he or won’t he hit the bullseye? Using Bayes’ Theorem, your prediction will be based on how the current match is going - and how he’s played in the past.

Pi is at the center of all circles.

The first digits of numbers in a data set aren't distributed equally. And now you know more than a lot of fraudsters do – and should – when they're making up their phony numbers.
Off to nab a would-be criminal?
Preventing crime before it happens, while saving resources, sounds like a great use of big data. But these calculated probabilities raise big questions about civil liberties.
