Random errors - Random errors can be evaluated through statistical analysis and can be reduced by averaging over a large number of observations. Systematic errors - Systematic errors are difficult to detect and cannot be analyzed statistically, because all of the data is off in the same direction (either to high or too low). Spotting and correcting for systematic error takes a lot of care.
These errors occur due to chance. These errors tend to cancel to each other in long run. These errors are random. They are not the results of any prejudice or bais.

Some of the reasons are: Systematic measurement errors. Random measurement errors. Poor use of equipment. Recording errors. Calculation errors. Poor plotting. Wrong model.

why is it important to identify errors in an experiment
The polarity of a random error refers to whether the error is positive or negative relative to the true value. In statistical analysis, random errors can be equally likely to be positive or negative, and their effect should cancel out when many measurements are averaged. Monitoring polarity can help identify biases or systematic errors in data collection or measurement processes.
Random errors can be parallax and from changes in the environment.
Punctuation
Random measurement errors of the same physical quantity if small, should over time cancel, while systemic measurement errors will not. Reading an instrument may produce random errors. If the same person reads it, there is a chance of systemic errors, so having separate individuals make independent readings is one way of reducing systemic error. Errors in calibration of equipment produces systemic errors. Sometime minor flucuations in environment causes highly sensitive equipment to generate random errors. However, using an instrument in an environment that is outside its working range can cause systemic errors.

The main source of random errors is the human factor. People make mistakes all the time. An error can sometimes lead to a very big mistake when the error is not corrected.
Two types of errors in physics are systematic errors, which result in measurements consistently being either higher or lower than the true value, and random errors, which occur randomly and can affect the precision of measurements. Systematic errors are usually due to equipment limitations or procedural mistakes, while random errors are caused by unpredictable variations in measurements.
Maximum Random Error is often calculated by subtracting the average from the data point farthest from the average.
