Lesson overview

Statistics

Data can be organised in different ways. Tables list information clearly, pictograms use repeated symbols, and bar charts compare values using bars. We can read each type carefully to find facts and compare amounts.

Read a table

A table helps us see each category and its value clearly.

FruitVotes
Apple6
Banana4
Pear5

Look along the row to match the label and the number.

Read a pictogram

A pictogram uses symbols to show amounts.

Key: each dot = 1 vote

Count the symbols carefully using the key.

Read a bar chart

Longer bars show larger amounts.

Compare the bar lengths and the values shown.

Worked example

Which fruit got the most votes in the table?

FruitVotes
Apple6
Banana4
Pear5
  1. Read each row in the table.
  2. Apple has 6 votes, Banana has 4 and Pear has 5.
  3. 6 is the greatest number.
  4. So Apple got the most votes.

Try it

Use the key or labels carefully, then compare the values shown.

Question 1

Common mistakes

Watch for these when working through the lesson.

  • Ignoring the key in a pictogram.
  • Reading the category but not the value.
  • Comparing bar lengths without checking the labels.
