Statistics can be a tricky self-learn adventure, as a lot of the field is non-intuitive and sometime counter-intuitive. I would usually advise, for anything beyond rudimentary statistics, to have some sort of mentor (traditional teacher style, online, whoever you can get). Especially since it is easy for a small error to make a large difference in your conclusion.

However, as with any learning there is no ubiquitous "best place". Nor is there a universal "best method". Generally, you need to find what works for you - and I can almost guarantee it is going to be a combination of different mediums. You'll want reference books for the heavy lifting, videos for engaging, interactive content for practice, etc.
