What are pilot studies?

Pilot studies are small scale experiments carried out before the larger experiment.

2
New cards

Why are pilot studies important?

Pilot studies are important because:

  • They are used to help plan procedures, assess validity, and check techniques

  • They allow evaluation and modification of the experiment.

  • They can be used to determine the appropriate range of values for the independent variable.

  • They can be used to establish the number of repeats required to give a representative value for each independent datum point.

3
New cards

What must be done to ensure an experiment is valid?

To ensure an experiment is valid, variables must be controlled so that any measured effect is likely to be due to the independent variable.

4
New cards

What is needed for an experiment to be considered reliable?

For an experiment to be reliable, consistent values should be achieved in repeats and the independent replicates

5
New cards

What does it mean if something is accurate?

If something is accurate, it means that data, or means of data sets are close to their true value.

6
New cards

What does it mean if something is precise?

If something is precise, it means that measured values are close to each other.
