# Step 2

This week you are revising data handling. You will be using tally marks, frequencies, pictograms and bar charts.

Data is a collection of information gathered by observation, questioning or measurement.

Data is often organised in tables, graphs or charts for us to investigate and analyse.

Bar charts are also known as bar graphs.

Remember if you are finding this work too easy, you can try Step 3. Try Step 1 if this work is too tricky.

Be creative. You can share your work by taking a photograph and sending it to the school Facebook. We would love to see your survey results.
