小老弟好！你們年輕人，朝氣蓬勃，象早晨八九點鍾的太陽，世界是你們的！

小老弟英文不錯，想法也不錯，做事的切入點也不錯！歡迎留在美國跟我們入夥！（不要介意有些中國人的冬烘勁，什麽“要做碼工為什麽要讀統計，讀了統計為何要做碼工”，那種是典型的冬烘先生 -- simple-minded and out of sense.）

好了，回答您的問題：

1. What are the differences between data analyst and data scientist?

A lot! Data analyst is entry-level job, for somebody who can work on data and dig out information for business support, this is will be very likely the first job you'll get. At this entry-level job, you will receive some supervision, and you'll pick up lots of experience, then you go two paths: project management or more senior level analyst.

A data scientist job will require much more! That's a job for somebody who can beat any issue with data: No data at all? He knows how to get it; Data storage and security? yes, digging out info that nobody knows? yes. Typically, this is a person with Ph training in hard-core science, lots of quant, lots of coding, and lots of critical thinking.

2. What are the main skills required to be a data analyst?

The best way to get you into the door is: SAS or R, or Both of them!:) R is a good start, you pick up R you get lots of experience at general computing. By reading the manual, you learn lots of stats, too:).

Hope it helps you any!
