Maths Quiz - Handling Data (Year 4) (Answers)
KS2 Maths involves learning about data handling. In Years Three and Four, you'll discover how to collect and record information using tallies or surveys. After that, you'll explore presenting and understanding data through various graphs, charts, and diagrams.
Collecting data and putting it into diagrams, graphs, tables, and charts helps us organise and make sense of what we've gathered. This is called interpreting data. It's essential to know which data goes into specific diagrams or charts to ensure others can understand your discoveries. For example, a survey about vehicles might use a pictogram with cars and lorries, while one about favourite colours might use a colourful pie chart.
