Experimental Error. In conducting an experiment a person encounters one or more of three general types of errors: human error, systematic error, and random error. Human error (a mistake) occurs when you, the experimenter, make a mistake.Examples would be when you set up your experiment incorrectly, when you misread an instrument, or when you make a mistake in a calculation. Human errors are not a source of experimental error; rather, they are experimenter's error.Do not quote human error as a source of experimental error.ystematic error is an error inherent in the experimental set up which causes the results to be skewed in the same direction every time, i.e., always too large or always too small. One example of systematic error would be trying to measure the fall time of a ping pong ball to determine the acceleration due to gravity.
