Write one number every evening: how many mangoes fell. Is that data?

Yes. This track shows what data is. It also shows what to do with it.

What this track covers

• What is data? — facts you collect and keep.
• Kinds of data — numbers, words, pictures, video and sounds.
• Groups — sorting mixed answers into a few clear groups.
• Tally marks — one mark per answer, counted in fives.
• Pictographs — one picture means a set amount.
• Bar charts — a taller bar means a bigger count.

Your maths book has a chapter on data handling. It uses the same ideas. Try each idea in its lab.
