Across
- 5. Something that is changed in an investigation. The independent variable usually has an effect on the dependent variable.
- 11. Data of the quantities of things we can count or measure. Examples of quantitative observations include number, length, mass, temperature or time.
- 12. Data that you have collected yourself
- 13. A measurement done multiple times to test how reliable it is. Three repeat trials with similar results can improve the reliability of an investigation.
- 15. An information source based on trusted evidence. Reliable resources include scientific articles, research bodies and books written by experts.
- 17. Data associated with measurements that can have unlimited values. Examples of continuous data include measurements of time, weight and speed.
- 18. data of the qualities of what we can see, hear or touch
- 19. Something that is kept the same in an investigation.
Down
- 1. A question that has a measurable outcome.
- 2. Information gained from websites, books and articles.
- 3. A review by scientific experts to check the quality of research before it's published
- 4. Something that is measured in an investigation
- 6. A list of all the references used during a research project
- 7. Data that is limited to a fixed range of values. Examples of discrete data include colours, types of animals and shoe sizes.
- 8. A testable prediction about the outcome of an investigation. A _________ is usually written as an "if...then..." statement.
- 9. Pieces of information obtained by observation or measurement
- 10. A value that can change or be different in an investigation. There are three types of variables – independent, dependent and controlled.
- 14. error, An error that doesn't follow a pattern. A random error means that all measurements are wrong by different amounts.
- 16. A drawing that illustrates an experimental setup.
