Full outline
SQL, spreadsheets, statistics, Python and visualisation — plus the communication skills that turn a correct analysis into an acted-upon one.
01Foundations
The tools you will use every single day.
- SQL
The non-negotiable core skill. Most analyst work is a query away.
- Spreadsheets
Still the most widely used analysis tool on earth. Fluency here buys enormous credibility.
- Statistics that matter
Enough to avoid confidently reporting noise as signal.
- Data cleaning
Where most of the job actually goes. Do it reproducibly.
- SQL
02Analysis & Visualisation
From query to something a director will read.
- Python for analysis
pandas takes over where spreadsheets run out of room.
- Visualisation
The chart is an argument. Choose the form that makes the argument honestly.
- BI tools
Dashboards that people return to, rather than admire once.
- Communicating findings
An analysis nobody acts on has zero value. This is the skill that gets you promoted.
- Python for analysis
