Data Analysis
Settle the question first, then go anywhere near the data
The tools are free and open datasets are plentiful, so the barrier is the question: without a clear one, even clean data only yields pretty meaningless charts. In practice cleaning consumes most of the time, which courses rarely convey. Practising on data you care about — your spending, your training, films you watched — sustains it.
First stepWrite down one specific question, find a public dataset about it, clean it in a free tool, and make one chart that answers it.
