Exam Skills – Interpreting Data
Learning outcomes
I will be able to:
State simple conclusions from tables and graphs
State more detailed conclusions (2 or 3 mark questions)
Respond appropriately to the command words describe and explain
Numeracy Objective
Ensure graphs and tables have titles and units.
REMEMBER: units are put into brackets.
Literacy Objective
Correct tense and verb agreement. You must use the correct version of the verb to match the tense. E.g. I see / I saw I do / I did.
Main errors are:
We was Correct to: We were.....
Presentation reminders
Underline titles and dates.
Include full date annotation.
Use a pencil and ruler where appropriate for diagrams and tables.
BfL reminders
Reminder about phones/headphones given at start of lesson. If phones out after, the teacher will confiscate until the end of the lesson.
Maintain a calm, learning environment.
No eating, drinking or shouting out.

2. The perfect CONCLUSION should start:
Simple Conclusions
The perfect CONCLUSION should start:
As __________ increases, _________ _________
Write what the dependent variable is here
Choose the right word: increases, decreases or stays the same
Write what the independent variable is here

3. More detailed conclusions
As THE NUMBER OF BLADES increases, the OUTPUT VOLTAGE IN VOLTS INCREASES… (1st mark)
… up to 4 blades, then increasing the number of blades doesn’t affect the output voltage. (2nd mark)
Number of blades

4. More detailed conclusions
As the wind speed increases the power output increases…
(1st mark)
… up to 14 metres per second where it reaches a maximum power output and stays the same...
(2nd mark)
… up to 25 metres per second where it drops to zero power output for higher speeds
(3rd mark)

5. More detailed conclusions
You could have to write conclusions from graphs as well.
As the pH increased the time for no starch to be detected decreased…
(1st mark)
… up to pH 7.0 where it was 1..5 minutes...
(2nd mark)
… after pH 7.5 the time increases again
(3rd mark)

6. NEVER use the word IT in a conclusion.
More detailed conclusions
NEVER use the word IT in a conclusion.
As the area increases, it increases.
What increases?
If there is any doubt you won’t get the mark.

7. Conclusions Quiz
State all conclusions that can be drawn from the graph

8. Conclusions Quiz
State all conclusions that can be drawn from the table

9. Conclusions Quiz
State all conclusions that can be drawn from the graph

10. Conclusions Quiz
State all conclusions that can be drawn from the table

11. Conclusions Quiz
State all conclusions that can be drawn from the table

12. Conclusions Quiz
State all conclusions that can be drawn from the graph

13. Conclusions Quiz
State all conclusions that can be drawn from the graph

14. Conclusions Quiz
State all conclusions that can be drawn from the table

15. Directly Proportional
Data is DIRECTLY PROPORTIONAL if the graph
would come out as a STRAIGHT LINE through the origin…
Or if the numbers in the table double in both columns
𝑥∝𝑦

16. Directly Proportional
When 10 doubles to 20, 2 doubles to 4
But when 20 doubles to 40, 4 doesn’t double to 8 (it goes to 16)
So the data is NOT directly proportional

17. Directly Proportional

18. DESCRIBE means say WHAT is happening
Describe and Explain
DESCRIBE means say WHAT is happening
EXPLAIN means say WHY it is happening
This type of question DOES NOT need any science knowledge because you just say what the graph, table or diagram shows. EASY
This type of question DOES need science knowledge. EASY… if you’ve revised.

19. Describe and Explain Describe the differences between the two people
Explain the differences between the two people

20. Describe and Explain Describe the trend shown in the graph
Explain the trend shown in the graph

21. Describe and Explain Describe the trend shown in the graph
Explain the trend shown in the graph

22. Describe and Explain Describe the trend shown in the graph
Explain the trend shown in the graph
