Fascinating Fact:

Weather forecasts are based on huge amounts of data collected from satellites, ships, and weather stations.

In KS3 Maths, you’ll explore how data is gathered and organised before it is graphed or analysed. You’ll learn about populations and samples, design fair survey questions, choose sensible data types, and record responses clearly so conclusions are trustworthy.

Key Terms

Population: The whole group you want information about, such as all pupils in a school.
Sample: A smaller group selected from the population to represent it.
Primary data: Information you collect yourself (e.g. a survey); secondary data is collected by someone else.

Frequently Asked Questions (Click to see answers)

What is the difference between primary and secondary data?

Primary data is gathered by you directly, like a questionnaire. Secondary data comes from existing sources, such as books, websites, or official statistics.

How big should a sample be at KS3?

Use the largest practical sample you can. It should be large enough to represent different groups fairly, not just your friends or one class.

How do I avoid bias when collecting data?

Ask neutral questions, include all reasonable answer options, sample from a wide range of people, and record results consistently using a clear table or tally chart.
