What Is A Good Percent Error

The experimenter may measure incorrectly, or may use poor technique in taking a measurement, or may introduce a bias into measurements by expecting (and inadvertently forcing) the results to agree with Online Web Apps, Rich Internet Application, Technical Tools, Specifications, How to Guides, Training, Applications, Examples, Tutorials, Reviews, Answers, Test Review Resources, Analysis, Homework Solutions, Worksheets, Help, Data and Information for Engineers, A high percent error must be accounted for in your analysis of error, and may also indicate that the purpose of the lab has not been accomplished. have a peek at these guys With this method, problems of source instability are eliminated, and the measuring instrument can be very sensitive and does not even need a scale.

As a rule, gross personal errors are excluded from the error analysis discussion because it is generally assumed that the experimental result was obtained by following correct procedures.
