Define reliability

* Measures the degree to which a measurement or test gives consistent and accurate results, and indicates the extent to which the instrument produces consistent and stable results over time or across different conditions.


* Ensures data collected is trustworthy and can be replicated or generalized.

Define validity

* If a test or measurement accurately measures what it intends to measure.
* It assesses whether a test is measuring what it claims to measure and whether the results are meaningful and reliable.
* Validity is crucial in ensuring that the conclusions drawn from a test or measurement are accurate and can be generalized to the larger population or context.

Define accuracy

* Degree of correctness or precision in measurements, calculations, or data.
* Measures how close a value or result is to the true or accepted value.

Define Reduce

Reducing the number of animals involved in trials

Define Refine

Hardship endured by trial subjects is minimized, is it humane?

Define Replace

* Substituting animal trials with alternatives e.g. cell cultures or computer models.


* Animal testing may only be used when there are no alternatives

Define Independent variable (x axis)

* The factor that you purposely change or manipulate in an experiment to see how it affects something else.
* It's the "cause" or the thing you're testing to understand its impact on the "effect" or the outcome you're interested in studying.

Define Dependent variable (y axis)

What you measure

Define Controlled variable

What you control
