There are many potential sources of error when designing and carrying out experiments.

Errors can arise from:

• the design of the experiment
• the measurement and sampling of data

Understanding the likely sources of error reduces the dangers of misinterpretation of errors. This requires adopting the appropriate protocols and calculation procedures. 

The method used in obtaining data must be repeatable by others.
