Experimental Error Vs Human Error
plan for the data acquisition and analysis is the heart of the experiment. Engineers also need experimental error calculation to be careful; although some engineering measurements have been made with fantastic accuracy (e.g., the speed of light is 299,792,458 1 m/sec.), for what factors cause experimental error most an error of less than 1 percent is considered good, and for 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 http://www.businessdictionary.com/definition/experimental-error.html 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 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 https://courses.cit.cornell.edu/virtual_lab/LabZero/Experimental_Error.shtml 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 occur in either the physical quantity being measured, the measurement process, or both. We will outline statistical procedures for handling this type of error. In reporting experimental results, a distinction should be made between "accuracy" and "precision." Accuracy is a measure of how close the measured value is to the true value. A highly accurate measurement has a very small error associated with it. Note that in experimental work the true value is often not known, and thus what

Moving Wall The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available in JSTOR shortly after publication. Note: In calculating the moving wall, the current year is not counted. For example, if the current year is 2008 and a journal has a 5 year moving wall, articles from the year 2002 are available.
