🛎️ What are Tally Mark Charts?
- Tally marks are used to count data as it is collected (e.g. number of cars passing).
- Marks are grouped in fives to make totals quicker and avoid miscounting.
🛎️ How to Read a Bar Chart?

- Read the number on the axis to find the value of each group.
🛎️ What is a Table Used For?
- Tables organise data so numbers can be read clearly and exactly.
- They save space and are useful when listing many values.
🛎️ When to Use Each Type of Chart
