Q & A
What is Data Science?
To gain insights into data through computation, statistics and visualization
The ability to take data—to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it—that’s going to be a hugely important skill in the next decades - Hal Varian
Why?

What Data Science Can Do?
- Predict whether a patient hospitalized due to a heart attach, will have a second heart attach. The prediction is to be based on demographic, diet & clinical measurement for that patient..
- Predict the price of a stock in 6 months from now, on the basis of company performance measures & economic data.
- Identify the risk factors for prostate cancer, based on clinical & demographic variables.
- It can also figure out whether a customer is pregnant or not by capturing their shopping habits from retail stores
- It also knows your age and gender, what brands you like even if you never told., including your list of interests(which you can edit) to decide what kind of ads to show you.
- It can also predict whether or not your relationship is going to last, based on activities and status updates on social networking sites. Police departments in some major cities also know you're going to commit a crime.
- It also tells you what videos you've been watching, what you like to read, & when you're going to quit your job.
- It also guess how intelligent you are how satisfied you are with your life, and whether you are emotionally stable or not -simply based on analysis of the 'likes' you have clicked
this is actually just the tip of the iceberg
