本人master 是统计的，现在想慢慢学习一些关于data science 的东西，请大侠们给点
basic idea,谢谢
In data science related jobs, how big was the data set (how many parameters/
fields the dataset contained) you guys usually work on?
were there dirty data problems? was there sampling bias? how did you guys
solve those problems, anything need to learn particularly?
How are you used to getting your data ? What software languages have you
used for extraction?
What do you use to clean and/or analyze the data? what quantitative methods
are usually used?
