There is no such thing as an exact measurement. https://answers.yahoo.com/question/index?qid=20090929195114AAOJ4Dt If the mass of an object is determined with a digital balance reading to 0.1 g, the actual value lies in a range above and below the reading. This range is the uncertainty of the measurement. Remember every time you take a measurement, the last digit recorded represents a guess. If the same object is measured on a balance reading to 0.001 g the uncertainty is reduced, but https://ibchemistrysl.wikispaces.com/Errors+and+Uncertainty+in+Experimental+Data can never be completely eliminated. Every measurement has an inherent uncertainty. We therefore need to give some indication of the reliability of measurements and the uncertainties in the results calculated from these measurements. When processing your experimental results, a discussion of uncertainties should be included. When writing the conclusion to your lab report you should evaluate your experiment and its results in terms of the various types of errors. To better understand the outcome of experimental data an estimate of the size of the systematic errors compared to the random errors should be considered. Random errors are due to the accuracy of the equipment and systematic errors are due to how well the equipment was used or how well the experiment was controlled. We will focus on the types of experimental uncertainty, the expression of experimental results, and a simple method for estimating experimental uncertainty when several types of measurements contribute to the final result. Random errors: Precision (Errors inherent in apparatus.) A random error makes the measured value both smaller and larger than the true value. Chance alone determines if it is smaller or larger. Reading the scales of a balance, graduated cylinder, thermometer, etc. produces random errors. In other wo
be careful and competent so that mistakes do not happen. Experimental error DOES refer to the uncertainty about the accuracy of the results of http://www.ausetute.com.au/errors.html an experiment. There are two types of experimental errors in chemistry: https://books.google.com/books?id=KAiCCwAAQBAJ&pg=PA130&lpg=PA130&dq=is+evaporation+a+systematic+or+random+error&source=bl&ots=KilUaTm-sY&sig=qXpl8ZV_KoaKzIvXxW6rgBXvP5g&hl=en&sa=X&ved=0ahUKEwiSrqHov9_PAhWk6YMKHUdyCXIQ6 (a) random errors (or indeterminate errors) (b) systematic errors (or determinate errors, or inherent errors) Random errors 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 experimental error 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 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 of experimental errors 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 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'

The Hydrological Cycle is a process of constant water exchange or water circulation in the hydrosphere, i.e. in the system of the atmosphere - Earth's surface – soil cover - upper lithosphere (to a depth of 2000 m). Water in the hydrosphere is liquid, solid or gaseous; during the hydrological cycle it moves under the effect of heat energy, gravitation and capillary forces, converting from a liquid to its solid state or gas, and back. The hydrological cycle is one of the major geophysical processes on the planet providing relative stability of natural c
