by what percent your experimental values differ from your lab partners' values, what is a good percent error in chemistry or to some established value. In most cases, a percent error or difference of less than 10% will types of errors in physics experiments be acceptable. If your comparison shows a 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 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 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 error

For example, a 5-10% error range on political polling is commonly accepted as reasonable. A similar http://physics.appstate.edu/undergraduate-programs/laboratory/resources/error-analysis rate for surgical error would be appaling and targets tend to be in the 0.1-1% range. In general, an error range of 5%-35% is acceptable, with 0-5% being exceptionally good, and over 35% meaning the data is unreliable or chaotic. An acceptable error range depends on the application.

Surveying has been likened to taste-testing soup – a few spoonfuls tell what the whole pot tastes like. The key to the validity of any survey is randomness. Just as the soup must be stirred in order for the few spoonfuls to represent the whole pot, when sampling a population, the group must be stirred before respondents are selected. It is critical reasonable percentage error that respondents be chosen randomly so that the survey results can be generalized to the whole population. How well the sample represents the population is gauged by two important statistics – the survey's margin of error and confidence level. They tell us how well the spoonfuls represent the entire pot. For example, a survey may have a margin of error of plus or minus 3 percent at a 95 percent level of confidence. These terms simply mean that if the survey were conducted 100 times, the data would be within a certain number of percentage points above or below the percentage reported in 95 of the 100 surveys. In other words, Company X surveys customers and finds that 50 percent of the respondents say its customer service is "very good." The confidence level is cited as 95 percent plus or minus 3 percent. This information means that if the survey were conducted 100 times, the percentage who say service is "very good" will range between 47 and 53 percent most (95 percent) of the time.
