Science

9. used for graphing discrete data
12. the variables that are kept the same in the investigation to ensure that the change in the independent variable is causing the change in what is being measured
14. used for graphing continuous data
17. data in which the values follow on from each other, such as when observing an event over time, age, temperature
18. the variable that is changed

1. data that contains numerical values eg height, speed, time
2. a brief summary of the investigation.
3. data in which the values are clearly separate and distinct from each other, eg gender, different brands of batteries, types of plants etc
4. data that is descriptive of observations, eg colour, taste
5. an experiment where only one factor is changed during the experiment and that is the factor that is being tested
6. performing the same experiment a number of times
7. the variable that is being measured in the investigation
8. a testable question or statement that is being investigated
10. having several samples of the same item tested at the same time
11. is usually collected by carrying out a scientific investigation
13. a step-by-step sequence of activities in an investigation
15. an estimate of the likelihood of adverse effects that may result from exposure to certain hazards
16. a treatment in the investigation where the variable being tested (ie independent variable) is absent.
