How Science Works Flashcards
What does repeatability mean?
If an experiment is repeatable then it means you can use the same method for the experiment again and get the same results.
What is reproducibility?
Reproducibility is the ability to conduct an experiment with different equipment and still get the same results.
What is an independent variable?
The independent variable is the one you choose to vary in your investigation?
What is the dependent variable?
The dependent variable is used to judge the effect of the independent variable.
What is a fair test?
A fair test is where the only variable that changes is the independent variable.
What is accuracy?
If your results are accurate then it means they are close to the true value.
What is precision?
If your results are precise then the range of your results are very close.
What is the difference between systematic and random error?
Systematic error is an error with the equipment that will result in consistent errors in all your results.
Random errors cause anomalies and single errors that can be corrected with repeated tests.
