📚 Resources 06 — Go Deeper on Data

All free, all optional. Data is a topic you can enjoy at any depth — from ten-minute videos to a full spreadsheet habit.

⚠️ Watch out: we link only to famous, stable homepages and tell you what to search for once there. Sites reshuffle their pages; their search boxes always know the way.

🎬 Video

• Crash Course Computer Science — search “Crash Course Computer Science” on YouTube The same energetic series recommended in Module 04. For this module, find the episode on data structures (around episode 14 in the series list): arrays (their name for lists), and the containers behind them, animated in twelve fast minutes. Best for: seeing the lesson’s containers drawn and moving. Fine to watch twice — most people do.

📖 Reading & interactive lessons

• Khan Academy — khanacademy.org A world-famous free learning site. Search it for “digital information” — a gentle unit on how text, images, and sound become numbers (bits and bytes), with short exercises after each section. Best for: anyone who wants the “everything is numbers underneath” idea from this lesson slowed down and practiced. No payment ever; an account is optional (only needed if you want it to remember your progress).

• W3Schools JSON introduction — w3schools.com W3Schools is the internet’s long-standing reference-and-tutorial site for web technology. Search it for “JSON introduction”: short pages with live “Try it yourself” boxes where you can edit real JSON in your browser and see what breaks. Best for: making the curly-brace format from the lesson and lab feel completely ordinary. Skim past anything mentioning JavaScript — you don’t need it yet.

🔧 Hands-on skills

• Google Applied Digital Skills — applieddigitalskills.withgoogle.com Google’s free library of practical, video-guided lessons. Search it for spreadsheets and pick a beginner lesson — organizing data in rows and columns, sorting, and asking whole-column questions. Best for: getting comfortable with tables, because a spreadsheet is the honest everyday cousin of every database you’ll meet in Module 12. Works in the browser; lessons are broken into short videos you follow along with.

How to use these

If you do only one thing: a beginner spreadsheet lesson from Google Applied Digital Skills. Tables are the single highest-value data skill for non-programmers — they show up in every office, every budget, and (as you now know) secretly inside every app. Then, next time you’re waiting for a bus, watch the Crash Course data structures episode and feel smug about recognizing everything.

When you’re ready: on to Part 3 and Module 07 — From Idea to App.
