Question
How does your experimental value compare to the generally accepted value (from a text or other source)? One way to respond to this question is to determine the percent difference between the value you reported and the generally accepted value. Note that if you simplify your units of slope, they will match those of the reported values of ag 3. Your determination of the percent difference does little to answer such questions as, "Is my average value for as close enough to the accepted value?" or "How do I decide if a given value is too far from the accepted value?" A more thorough understanding of error in measurement is needed. Every time you make a measurement, there is some random error due to limitations in your equipment, variations in your technique, and uncertainty in the best-fit line to your data. Errors in technique or in the calibration of your equipment could also produce systematic error. We'll address this later in the experiment. In order to better understand random error in measurement, you must return to your experimental apparatus to collect more data. 4.Explanation / Answer
Dear studen
The accepted value is a number or value that scientists and the public regard as true.
The experimental value is the value that you get in an experiment.
The absolute value of the difference between the two values (the "error") is your experimental error.
Error=|experimental value - accepted value|
The difference is usually expressed as percent error.
% error=[|experimental value - accepted value|/experimental value]×100%
For example, suppose that you did an experiment to determine the acceleration due to gravity got a value 9.70 m/s2
Your experimental value is 9.70 m/s2.
The theoretical value or accepted value is 9.8 m/s2.
The experimental error is =|9.8-9.70|=0.1 m/s2.
% error=[|9.70 - 9.8|/9.70]×100%=1.03%
