Random and systematic errors in laboratory

Webb• Random Errors: Random errors cause positive and negative deviations from the average value of a measurement. Random errors cancel by averaging, if the experiment is repeated many times. Upon averaging many trials, random errors have an effect only on the precision of a measurement. The effect of random errors is primarily on the precision. http://xmpp.3m.com/examples+of+constant+errors+in+research+marketing
