Data skills every modern career needs
Spreadsheets, basic SQL, and reading charts are becoming baseline skills — not just for analysts. Where to start, whatever your field.
"Data skills" used to mean a job title. It increasingly means literacy — the way word processing did a generation ago. Whatever your field, three specific skills now regularly separate the person consulted from the person who waits to be told.
Spreadsheets beyond the basics
Not just entering data — VLOOKUP/XLOOKUP, pivot tables, and conditional logic with IF statements. A professional who can turn a raw export into a pivot-table summary in twenty minutes changes how meetings around them go. This is the highest-return few hours of learning available anywhere.
Enough SQL to ask questions
You do not need to become a database engineer. SELECT, WHERE, GROUP BY, JOIN — four ideas that let you answer your own questions instead of waiting in a queue for someone else's report. Most people can learn them in a few weekends with data they already understand.
Reading a chart skeptically
The skill is not making charts; it is interrogating them. What is the axis hiding? Compared to what? Who is missing from the sample? Teams have learned to fear the confident person with one misleading chart — be the person who quietly asks the question that saves the quarter.
Start anywhere on this list — data courses on Dev Skill cover all three skills with practice data included.
