In this way, the discrepancies or errors are reduced Maintaining good experimental technique (e.g. reading from a correct position)Next: Systematic Errors Previous: Uncertainty Back To Measurement (A Level) shares Facebook Twitter Google+ Facebook Twitter Google+ Pinterest LinkedIn Digg Del StumbleUpon Tumblr VKontakte Print Email Flattr Reddit Buffer Love This Weibo Pocket Xing Odnoklassniki ManageWP.org WhatsApp Meneame Blogger Amazon Yahoo Mail Gmail AOL Newsvine HackerNews Evernote MySpace Mail.ru Viadeo Line Flipboard Comments Yummly SMS Viber Telegram Subscribe Skype Facebook Mes
be careful and competent so that mistakes do not happen. Experimental error DOES refer to the uncertainty about the accuracy of the results of an experiment. There are two types of experimental errors in chemistry: (a) random errors (or http://www.ausetute.com.au/errors.html indeterminate errors) (b) systematic errors (or determinate errors, or inherent errors) Random errors https://books.google.com/books?id=QylDlghxdwoC&pg=PA386&lpg=PA386&dq=evaporation+random+error&source=bl&ots=cPY_cw9Bm2&sig=Qg-Yz40o2wAJ8HWM8aqLaxEtvLc&hl=en&sa=X&ved=0ahUKEwjAoonFxdTPAhUV8YMKHVbiAakQ6AEIUzAJ result from random events which cannot be eliminated during the experiment. Systematic errors are errors inherent in the experiment and which can be determined and therefore compensated for. The goal in a chemistry experiment is to eliminate systematic error and minimize random error to obtain a high degree of certainty. Removal of uncertainty results in accuracy and precision. Mistakes experimental error Mistakes are NOT considered to be experimental errors. It is assumed that if an experimenter has made a mistake then he/she will discard the results of the experiment or calculation and start again, that is, results from an experiment that included mistakes would NOT be reported. Mistakes occur if the experimenter is careless, or, if the experimenter is incompetent. When the results of an experiment are reported, it is assumed that the experimenter was both careful of experimental error and competent. Would you like to see this example?

Remember, if you make a mistake during an experiment or calculation, you should discard what you have done so far and start again. You should not report the results of an experiment that includes mistakes. Mistakes are NOT the same as experimental errors. Experimental errors are either random or systematic errors as described below. Random Errors Random errors result from random events which cannot be eliminated during the experiment. Random errors usually result from the experimenter's inability to take exactly the same measurement in exactly the same way any number of times and get the exactly the same number. Examples of the sources of random errors are: fluctuation of the power supply during the use of electronic equipment such as an electronic balance using a contaminated reagent in a particular experiment experimenter being distracted while taking a measurement locating the bottom of the meniscus for volume measurements using pipettes, burettes, measuring cylinders, etc Since random errors cannnot be eliminated from the experiment, they are minimised by repeating the experiment a number of times until the uncertainty has b
