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 values differ from your lab partners' values, or to some established value. acceptable percent error chemistry In most cases, a percent error or difference of less than 10% will be acceptable. what is a good percent error in chemistry If your comparison shows a difference of more than 10%, there is a great likelihood that some mistake has occurred, and you should what is a good percent error range look back over your lab to find the source of the error. These calculations are 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 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 low percent error means 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. Incomplete definition (may be systematic or random) - One reason that it is impossible to make exact measurements is that the measurement is not always clearly defined. For example, if two different people measure the length of the same rope, they would probably get different results because each person may stretch the rope with a different tension. The best way to minimize definition errors is to carefully consider and specify the condition

The definition of percent error uses the absolute value of the difference between your value and the accepted value so it can never be negative.

It is perfectly fine to have percentage error>percentage uncertainty. All that means is that the experiment probably more accurate than precise. I think you already answered your own question Accuracy is how close your experimental value is to your to the literature value, which is measured by %error.Uncertainty is the equal chance of measuring something too high or too low, which is measured by uncertainty/ %unc.

Share this post Link to post Share on other sites CkyBlue Bag Global Moderator 650 posts Exams: May 2012 Posted January 15, 2012 In your typical chemistry experiment, a percentage error of 3% is rather small actually, so I wouldn't say it is inaccurate. Percentage error is due to systematic errors within the experiment, which are inherent problems with procedure. Systematic errors can
