Where to start learning? That's a touch question and an easy one at the same time: There's no one-fits-all solution. Find yourself a project and learn the tools you need to realize that.
If you want to go beyond, here's an ever-growing list of graduate and post-graduate training programs, but I'm sure many are missing. In case you know of more educational programs, please let me know.
A few I would like to specifically highlight:
Learno by the European Journalism Centre offers a set of online courses on specific data journalism-related topics like Cleaning data in Excel or Mapping for journalists. It's free of cost. Similar to this is the School of Data
Knight Center of the University of Texas was the first ddj MOOC I participated in - and it was awesome! You have weekly video tutorials, readings and little projects to work through each week. A crucial part is also to give feedback to others and thereby learn how to critique data visualizations. They do not only offer ddj courses, but also on other journalism topics. It's pretty low cost (60 to 90 dollars).
Open Tech School is a hybrid between online and offline courses: They have bunch of tutorials online (for example on Python and Javascript) and local groups that regularly meet up all across Europe. It's free of cost.
Columbia University's Lede Program is the one where I learnt coding. It's very expensive (roughly $14,000 US-dollar tuition fees for the shorter Lede12) and I believe the ability to learn journalism skills should not be linked to your income - however, this was worth every dollar.
If you want to get a very first grip on statistics, there's this great online course with additional resources by the British Royal Society of Statistics that you should definitely check out as a starting point.
