- [Woman] Let's go back to the beginning --
[gong]
last year, in fact -- to a world that was in the glory days
of the Information Age.
Information was everywhere.
- [computer]
- So much, in fact, that we were swimming
in a virtual ocean of it with wave after wave
bringing in more every day.
Our curious young student reveled in it.
His phone could seemingly answer any question
that popped into his mind.
Or so he thought.
It turned out that for his most important questions --
How to eat healthy?
What school should he attend? --
the more he waded through this vast sea of information,
the more confused he got.
- [Student] Why is this so complicated?
- Where could he find the answers?
Where should he invest his time?
He tried to learn P-values, R-squared,
regression analysis and more.
It was so complex, it seemed to be written in code
that made no sense to him.
- What is this?
- The answers to his questions seemed further away than ever.
Eventually, he came to the conclusion
that traditional methods would get him no further.
He would set out on a quest, traveling the globe to hunt
for the answers that these methods couldn't provide.
For nearly a year he traveled --
- Whoa!
- Through the world's remote regions,
[screaming]
[splash]
seeking out wise men and women,
studying ancient artifacts,
and unearthing arcane legends.
- Ooh shiny!
- Throughout his travels, he continued to find clues
of a remote place, a place of learning,
and of a man who could swim through this sea of information,
a man who knew how to find the answers,
a master of metrics.
After struggling for so long, it seemed he had finally found
his destination.
Which brings us back to now.
- Is there really a master who can teach me to find
the answers I'm looking for?
- Indeed.
It is Master Joshway you seek.
- Master Joshway.
- Yes, in the outside world, he was known as Josh Angrist.
- So he's a master of data science and statistics?
- Oh! There is so much of this noise in the world.
So much confusion.
He -- [loud cry and sword slice]
The answers you seek --
[loud yell and crash]
The answers you seek are rooted
in a simple but deep concept, cause and effect.
It is only through econometrics, the original data science
that you can come to know the path from cause to effect.
[claps]
And in order to grasp econometrics, you must learn to master
the legendary furious five.
These are the primary weapons used in econometrics.
Without--
[loud cry]
The journey of a thousand miles begins
with one step.
Mastering Econometrics is a free online course
that teaches you how to use the legendary furious five.
Econometrics is a journey, grasshopper.
