Parallax error - what type types of experimental error of error is it? Oct 24, 2006 #1 skyglow1 My friends are having an argument as to whether parallax error is systematic or random error. We have tried
Sources Of Error In Experiments
looking all around in books/internet etc but nothing mentions what type of error it is. Any help would be appreciated :) skyglow1, Oct 24, 2006 Phys.org - latest science and technology news stories on Phys.org •Unusual quantum liquid on crystal surface could inspire future electronics •When quantum scale affects the way atoms emit and absorb particles

I'm not sure under what circumstances this error is encountered in regard to your question. Parallax simply involves a different viewpoint. If I understand your question correctly, then it is a systematic error, not random. It would mean that the observer and the obsrerved are not in the same spatial relationship during multiple observations. Danger, Oct 24, 2006 Oct 24, 2006 #3 Integral Staff Emeritus Science Advisor Gold Member Parallax is a systematic error. It should be very repeatable, and can be eliminated with some care. Integral, Oct 24, 2006 Oct 24, 2006 #4 FredGarvin Science Advisor Agreed. Paralax is not a function of the operation of the experiment. It is an error you usually have control over and can repeat (like Integral mentioned). Look here: http://www.chem1.com/acad/webtext/matmeasure/mm4.html note the section on systematic error.

or experimental values. This calculation will help you to evaluate the relevance of your results. It is helpful to know by what percent your experimental sources of error in physics values differ from your lab partners' values, or to some established value. In
Experimental Error Formula
most cases, a percent error or difference of less than 10% will be acceptable. If your comparison shows a types of experimental error chemistry difference of more than 10%, there is a great likelihood that some mistake has occurred, and you should look back over your lab to find the source of the error. These calculations are https://www.physicsforums.com/threads/parallax-error-what-type-of-error-is-it.139823/ also very integral to your analysis analysis and discussion. 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. Percent error: Percent error is used when you are comparing your result to a known or accepted value. It is the absolute value of the difference of the values http://physics.appstate.edu/undergraduate-programs/laboratory/resources/error-analysis divided by the accepted value, and written as a percentage. Percent difference: Percent difference is used when you are comparing your result to another experimental result. It is the absolute value of the difference of the values divided by their average, and written as a percentage. A measurement of a physical quantity is always an approximation. The uncertainty in a measurement arises, in general, from three types of errors. Systematic errors: These are errors which affect all measurements alike, and which can be traced to an imperfectly made instrument or to the personal technique and bias of the observer. These are reproducible inaccuracies that are consistently in the same direction. Systematic errors cannot be detected or reduced by increasing the number of observations, and can be reduced by applying a correction or correction factor to compensate for the effect. Random errors: These are errors for which the causes are unknown or indeterminate, but are usually small and follow the laws of chance. Random errors can be reduced by averaging over a large number of observations. The following are some examples of systematic and random errors to consider when writing your error analysis. In
