How do I master data analysis and data mining?

R and Python are good tools in working with data analysis and data mining.

I would recommend the Data Science Specialisation on Coursera (total of 9 free courses) to learn how to program and analyze data using R.

For python, there is a book called “Python for Data Analysis” which talks about data wrangling using packages including Pandas and Numpy. I’m currently reading this book now and it has lots of examples.
