Demonstrate that you can turn data into Money.

The how is intentionally left open. As a scientist,you need to be capable of owning the entire process. You need the hustle to acquire your dataset and the mathematical ability to derive an advantage from it.

Can't be learned at school. You have it or you don't.

It's OK if you aren't able to "realize" the making Money part due to real world constraints. (For example a demonstrable investment opportunity that you can't personally invest in because you don't have funds to play with)
