value unless you can communicate that knowledge to others. Imagine that you are writing your report for a technically literate person who does not know what you did or why. Graphs A first percent error when expected value is zero major error is that many graphs do not present data effectively. In order to make an effective graph, you should follow some standard conventions: Use either linear or log scales on both x and y axes. Many students used arbitrary scales or simple labelled their data points on the x and y axes. Standard scales make it easier to interpret a graph. Nonstandard scales make how to calculate relative error when true value is zero? data hard to decipher. Make your graphs at least 7.5 cm (three inches) tall and 10cm (four inches) wide to ensure clarity. Smaller graphs hide smaller variations in the data; computer-generated graphs are great but not necessary. Label all axes and traces. Also, do not put more than two traces on a graph unless you are trying to show a progression of data. If there are two traces or more on a graph, use different marks for the data points; i.e. x's for trace one, o's for trace two, etc. Use two or more colors for the traces if practical. Tables Another weakness in lab reports is the style of tables used. Use a vertical table (an independent variable column next to the dependent variable columns) whenever you have the numerical data available. Please do not use horizontal tables; they are very hard to read and thus do not present your data effectively. Use your ruler to organize your tables and make them easier to read. Error Analysis Writing: "...the measurements agree pretty well with the expected values..." does not mean a thing. It is important to do good error analysis. Usually, this should be done

The equation for % error is [absolute value(calculated value - theoretical value) / theoretical value] * 100, but 0 can't be in the denominator, because you can't divide by 0.

Use the value epsilon(a small number) as theoretical value, do your calculations based on this. I assume you are working with extremely small numbers (<0.001) Source(s): vcs7578 · 9 years ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse You may add a number to both the values ie theoretical and observed value...for an example if your theoretical value is 0 and observed value is 2...By adding 1 for example on both sides and by applying it on formula (theoretical value-Observed value)/Theoretical Value X 100::::[(0+1)-(2+1)]/(0+1) x 100=200%....This adjustment can be called as Zero level adjustment. anush · 2 years ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse There is no percent error if the answer is zero. the only way to state the answer is: 0. +/- (absolute error) brandlet · 9 years ago 1 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse state the answer is: 0. +/- (absolute error) ok thanks sanjeewa · 9 years ago 1 Thumbs up 0 Thumbs down Comment Add a comment Submit · ju

The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he dete
