Chapter 2: Basic Data Concepts
Data is raw, unorganised facts. When we organise and analyse data, it becomes information that helps us decide things.
Learning outcomes
- Define data and information with examples
- Classify data as numbers, text, images, audio or video
Activities
- Collect class attendance and present as data
Worked examples
Read through these first, then try the practice below.
Example 1 — Data vs Information
A list of every student's marks in a test is _____. The class average computed from that list is _____.
Solution: The list is data; the average is information — it summarises the raw data so we can act on it.
Example 2 — Classify the data
Tag each item: (a) a photo of a leaf, (b) the temperature 28°C, (c) a song clip, (d) the word 'apple'.
Solution: (a) image, (b) numeric, (c) audio, (d) text. Modern AI systems learn from all of these data types.
