We're using the word "wrong" to emphasize a point. All experimental data is imperfect. Scientists know that their results always contain errors. However, one of their goals is to minimize errors, and to be aware of what human error examples the errors may be. Significant digits is one way of keeping track of how much human error synonym error there is in a measurement. Since they know that all results contain errors, scientists almost never give definite answers. They are far

more likely to say: "it is likely that ..." or "it is probable that ..." than to give an exact answer. As a science student you too must be careful to learn how good your results are, http://www.businessdictionary.com/definition/experimental-error.html and to report them in a way that indicates your confidence in your answers. There are two kinds of experimental errors. Random Errors These errors are unpredictable. They are chance variations in the measurements over which you as experimenter have little or no control. There is just as great a chance that the measurement is too big as that it is too small. Since the errors are equally likely to be high as low, averaging a http://www.digipac.ca/chemical/sigfigs/experimental_errors.htm sufficiently large number of results will, in principle, reduce their effect. Systematic Errors These are errors caused by the way in which the experiment was conducted. In other words, they are caused by the design of the system. Systematic errors can not be eliminated by averaging In principle, they can always be eliminated by changing the way in which the experiment was done. In actual fact though, you may not even know that the error exists. Which of the following are characteristics of random errors? Check all that apply. a) doing several trials and finding the average will minimize them b) the observed results will usually be consistently too high, or too low c) proper design of the experiment can eliminate them d) there is no way to know what they are It is not easy to discuss the idea of systematic and random errors without referring to the procedure of an experiment. Here is a procedure for a simple experiment to measure the density of rubbing alcohol (iso-propanol). Materials: digital electronic balance that can be read to 0.01 g 100 mL graduated cylinder, marked every 1 mL iso-propanol Procedure: Find and record the mass of the empty, dry graduated cylinder. Fill the graduated cylinder about 3/4 full of the alcohol. Record the volume of the alcohol i
