  1. 1. assessment 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.
  2. 6. chart A way of presenting data when one variable is discrete or categoric and the other is continuous.
  3. 10. A variable that has values that can be any number.
  4. 12. chart A way of presenting data when one variable is discrete or categoric and the other is continuous.
  5. 13. graph A way of presenting results when there are two numerical variables.
  6. 14. The difference between the lowest and highest values a variable can have.
  7. 16. When you repeat measurements in an investigation and get similar results they are repeatable.
  8. 17. The doubt in the result because of the way that a measurement is made.
  9. 18. The difference between the highest and lowest measurements of a set of repeat measurements.
  10. 20. A quantity that can change, for example, time, temperature, length, mass.
  11. 21. A result that is very different from the other measurements in a data set.
  12. 22. 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. 23. How sure you are of your conclusion based on the data/
  14. 24. Words or numbers that you obtain when you make observations or measurements.
  15. 26. A variable that can only have whole-number values.
  16. 28. of best fit A smooth line on a graph that travels through or very close to as many of the points plotted as possible.
  17. 29. variable A variable that you have to keep the same in an investigation.
  18. 30. error An error that causes there to be a random difference between a measurement and the true value each time you measure it.
Down
  1. 2. error An error that causes there to be the same difference between a measurement and the true value each time you measure it.
  2. 3. A statement that says what you think will happen.
  3. 4. What you write down to say what you have found out during an investigation.
  4. 5. To discuss the quality of data collected during an investigation and suggest improvements to the method.
  5. 7. Close to the true value of what you are measuring
  6. 8. variable A variable you change that changes the dependent variable.
  7. 9. An experiment or set of experiments designed to produce data to answer a scientific question or test a theory.
  8. 11. A variable that has values that are words.
  9. 15. The process of looking at data and writing about what you have found out.
  10. 16. When other people carry out an investigation and get similar results to the original investigation the results are reproducible.
  11. 19. Carefully looking at an object or process.
  12. 25. This describes a set of repeat measurements that are close together.
  13. 27. A description of how you will use equipment to collect valid data to answer a scientific question.
  14. 31. variable A variable that changes when you change the independent variable.
