An order worth learning it in

A list of ten skills is the same unhelpful answer a catalogue gives, just sorted. This is where to actually start.

1

Start here

Essential to the role, and reachable from a standing start. Everything below rests on these.

  • Python
  • SQL
  • Bayesian statistics
  • Git
2

Then this

The rest of what the role is assessed on. Harder, and it builds on the foundation above.

  • R
  • Experimental design
  • Regression modeling
3

What sets you apart

Not what gets you hired, but what separates doing the job from being trusted with it.

  • Power BI or Tableau
  • SAS

You almost certainly have some of this already.

That is the point of starting from the role rather than a course. Upskili checks what you can do, then builds a path across only the gap.
