present is essential if data are to be used wisely, whether the data being considered were measured personally or merely read from manufacturer's data sheets for define experimental error a material or component. In medical research, biology, and the social sciences, the list two good scientific reasons to account for any experimental error plan for the data acquisition and analysis is the heart of the experiment. Engineers also need to be careful; although experiment definition statistics some engineering measurements have been made with fantastic accuracy (e.g., the speed of light is 299,792,458 1 m/sec.), for most an error of less than 1 percent is considered good, and for http://www.businessdictionary.com/definition/experimental-error.html a few one must use advanced experimental design and analysis techniques to get any useful data at all. Making measurements and analyzing them is a key part of the engineering process, from the initial characterization of materials and components needed for a design, to testing of prototypes, to quality control during manufacture, to operation and maintenance of the final product. Reported experimental results should always https://courses.cit.cornell.edu/virtual_lab/LabZero/Experimental_Error.shtml include a realistic estimate of their error, either explicitly, as plus/minus an error value, or implicitly, using the appropriate number of significant figures. Furthermore, you need to include the reasoning and calculations that went into your error estimate, if it is to be plausible to others. An explicit estimate of the error may be given either as a measurement plus/minus an absolute error, in the units of the measurement; or as a fractional or relative error, expressed as plus/minus a fraction or percentage of the measurement. The advantage of the fractional error format is that it gives an idea of the relative importance of the error. A 10-gram error is a tiny 0.0125% of the weight of an 80-kg man, but is 33.3% of the weight of a 30-g mouse. Errors may be divided roughly into two categories: Systematic error in a measurement is a consistent and repeatable bias or offset from the true value. This is typically the result of miscalibration of the test equipment, or problems with the experimental procedure. On the other hand, variations between successive measurements made under apparently identical experimental conditions are called random errors. Random variations can occu
