ABSTRACT
Systematic error is constant throughout the set of readings and arises, as the experimental set up is different from that assumed in theory. Random error is scatter of the data gathered in identical repeated experiments. Random error has a definite value that can be determined by statistical methods. Random errors can be removed by recording a large number of measurements. Suppose, the measurements are taken at different times with a clock that runs fast or slow, systematic error would be incorporated in the data. It is usually difficult to find out the systematic errors. The random error can be removed by repeating the measurements under identical conditions. The arithmetic mean of the multiple data points approaches near the true value. In short, the errors may be estimated by statistical methods.
