- 3. A description of how you will make it less likely that people will be injured, or equipment damaged, and what to do if this happens.
- 5. A way of presenting data when one variable is discrete or categoric and the other is continuous.
- 7. An error that causes there to be a random difference between a measurement and the true value each time you measure it.
- 9. A quantity that can change, for example, time, temperature, length, mass.
- 10. When you repeat measurements in an investigation and get similar results they are...

- 21. A variable that has values that can be any number.
- 23. A variable that you have to keep the same in an investigation.
- 24. A variable that has values that are words.
- 25. Close to the true value of what you are measuring.
- 28. A statement that says what you think will happen.
- 29. An experiment or set of experiments designed to produce data to answer a scientific question or test a theory.

Down
- 1. The doubt in the result because of the way that a measurement is made.
- 2. This describes a set of repeat measurements that are close together.
- 4. A variable you change that changes the dependent variable.
- 6. When other people carry out an investigation and get similar results to the original investigation the results are reproducible.
- 8. Words or numbers that you obtain when you make observations or measurements.
- 11. The difference between the highest and lowest measurements of a set of repeat measurements.
- 12. An average of a set of data, found by adding together all the values in the set and dividing by the number of values in the set.
- 13. The difference between the lowest and highest values a variable can have.
- 17. A variable that changes when you change the independent variable.
- 20. An error that causes there to be the same difference between a measurement and the true value each time you measure it.
- 22. What you write down to say what you have found out during an investigation.
- 26. The process of looking at data and writing about what you have found out.
- 27. A variable that can only have whole-number values.
