built into them, but the statistics we'll do here requires only basic calculator competence and capabilities. Arithmetic Mean, Error, Percent Error, and Percent Deviation Standard Deviation Arithmetic Mean, Error, Percent Error, and Percent Deviation The statistical tools you'll either love or hate! These are the calculations that most chemistry professors use to determine your grade in lab experiments, specifically percent error. difference between percent error and standard error Of all of the terms below, you are probably most familiar with "arithmetic mean", otherwise known as an "average". Mean -- add all of the values and divide by the total number of data points Error -- subtract the theoretical value (usually the number the professor has as the target value) from your experimental data point. Percent error -- take the absolute value of the error divided by the theoretical value, then multiply by 100. Deviation -- subtract the mean from the experimental data point Percent deviation -- divide the deviation by the mean, then multiply by 100: Arithmetic mean = ∑ data pointsnumber of data points (n) Error = Experimental value - "true" or theoretical value Percent Error = Error Theoretical value ∗100 Deviation = Experimental value - arithmetic mean Percent Deviation = DeviationTheoretical value ∗100 A sample problem should make this all clear: in the lab, the boiling point of a liquid, which has a theoretical value of 54.0° C, was measured by a student four (4) times. Determine, for each measurement, the error, percent er
