ANALYSING DATA
Learning Objective
• Understand how to draw conclusions from data using good Science.
Starter- What makes a good graph?
Look at the graphs and think about which one is the best and why.

In Celsius 1.Can you spot the odd
(anomalous) result?
2. What do you think would be a more accurate result?
Anomalous result
What makes a good analysis?
1. Calculations and data on tables.
2. Draw a graph of the results, label axes and title the graph.
3. If appropriate draw a line or curve of best fit to your results.
4. Explain what the graph indicates about your results.
5. Explain what the results show using good Science.
