Introduction To Experimental Error And Main Points That Cause This Error

Experimental error is the error that is observed in the final result of an experiment. It’s the difference between the true value and observed value that comes from the experiment. It is also known as observational error.

The key points which mainly causes this error are as described below:

• Blunders (Mistakes).
• Human error.
• Sampling
• Error due to external influence.
• Not all measurements have well-defined value.
• Machine error.

This error can divided into two parts:

• Random error.
• Systematic error.

Random errors are the error which are caused due to incorrect value measures.

Systematic error is the error that is causes due to fault in the machinery. It can also refer to the error with a non-zero mean.
