Across
- 1. Measurements which there is very little spread about the mean value
- 3. Closeness to the true value
- 5. A possible explanation of some observations, which can be tested
- 7. If the original experimenter repeats the investigation using same method and equipment and obtains the same results
- 8. The maximum and minimum values of the independent or dependent variables; important in ensuring that any pattern is detected
- 9. A measure taken to reduce or remove a risk
- 11. Values in a set of results that are judged not to be part of the variation caused by random uncertainty.
- 13. The average of the numbers: a calculated "central" value of a set of numbers
- 14. The likelihood that a person may be harmed or suffers adverse health effects if exposed to a hazard
- 15. The variables which are actively maintained
- 17. Something noticed; either using our senses or with technology
Down
- 2. The variable which is changed or investigated
- 4. Have values that are labels e.g. names of plants or types of material
- 6. The variable which is measured
- 10. Something that can cause harm
- 12. A measure of level of detail possible with a piece of equipment
- 16. An idea which explains one or more accepted hypotheses, that is supported by lots of experiments and data, and makes new predictions that can be tested
- 18. The likelihood that a person may be harmed or suffers adverse health effects if exposed to a hazard
