Error Analysis Basics

these quantities should be presented in terms of Significant Figures. For example, the location of the arrow is to be determined in the figure below. It is obvious that the location is between 1 cm and 2 cm. error analysis physics The correct way to express this location is to make one more estimate based error analysis examples on your intuition. That is, in this case, a reading of 1.3 cm is estimated. This measurement is said to contain error analysis definition two significant figures. Note that there should only be one estimated place in any measurement. If data are to contain, say, three significant figures, two must be known, and the third estimated. Do not try to

locate the position of the arrow in fig. 1 as 1.351 cm. The following rules dictate the handling of significant figures. a Specify the measured value to the same accuracy as the error. For example, we report that a physical quantity is x = 3.45 ± 0.05, not 3.4 ± 0.05 and not 3.452 ± 0.05. b When adding or subtracting numbers, the answer is only good to the least accurate how to do error analysis number present. For example, 50.3 + 2.555 = 53.9 and not 52.855. c When multiplying or dividing, keep the same number of significant figures as the factor with the fewest number of significant figures. For example, 5.0 · 1.2345 = 6.2 and not 6.1725. Types of Errors Every measurement has its error. In general, there are three types of errors that will be explained below. Random Errors This type of error is usually referred to as a statistical error. This class of error is produced by unpredictable or unknown variations in the measuring process. It always exists even though one does the experiment as carefully as is humanly possible. One example of these uncontrollable variations is an observer's inability to estimate the last significant digit for a given measurement the same way every time. Systematic Errors This class of error is commonly caused by a flaw in the experimental apparatus. They tend to produce values either consistently above the true value, or consistently below the true value. One example of such a flaw is a bad calibration in the instrumentation. Personal Errors This class of error is also called "mistakes." It is fundamentally different from either the systematic or random errors stated above, and can be completely eliminated if the experimenter

Professor Sumner DavisThis video accompanies the Error Analysis exercise, providing students with an introduction to the theory and procedures.In many labs, you will be required to perform a detailed analysis of the data you have acquired to make quantitative statements about the properties of the physical world. A common question is, are your measurements consistent with a particular theory or not? This question can be answered only by careful analysis of systematic uncertainties and statistical error. The goals of this exercise are twofold. One is to introduce you to the basics of error analysis. The second is to familiarize you with the Matlab software that you will be using for data analysis . Ideally, this will serve as a guide during the acquisition and analysis of data throughout the advanced lab.http://advancedlab.org Kategori Utbildning Licens Standardlicens för YouTube Visa mer Visa mindre Kommentarer har inaktiverats för videoklippet.
