Trial and error definition is - a finding out of the best way to reach a desired result or a correct solution by trying out one or more ways or means and by noting and eliminating errors or causes of failure; also : the trying of one thing or another. All measurements have a degree of uncertainty regardless of precision and accuracy. When measuring a defined length with a ruler, there is a source of uncertainty and the measurement may. Calibrating Equipment: Just as random error can be reduced by averaging several trials, systematic error of. Trial and error definition, experimentation or investigation in which various methods or means are tried and faulty ones eliminated in order to find the correct solution or to achieve the desired result or effect. Trial and error is a fundamental method of problem solving. It is characterised by repeated, varied attempts which are continued until success,. ( The latter case can be alternatively considered as a changing of the problem rather than of the solution strategy: instead of " What chemical will work well as an antibiotic? Mistakes, such as incorrect calculations due to the improper use of a formula, can be and should be corrected.

An ' accurate' measurement means the darts hit close to the bullseye. The mean value computed from multiple trials averages out some of the random error; repeated measurements are required.
