Random and systematic errors are types of measurement error, a difference between the observed and true values of something.

Systematic errors and their causes There are systematic errors 1. caused by wrong decisions taken before the analysis, 2. caused by errors in the primary sampling technique, 3. caused by errors in sample handling, 4. caused by errors in sample dosage (including secon- dary dosage), 5. ...
The meaning of RANDOM ERROR is a statistical error that is wholly due to chance and does not recur —opposed to systematic error.

The choice of the perturbation timescale, and the trade-offs between reducing systematic or random errors, may depend on the intended application of the flux data. When only longer term flux estimates (e.g., monthly or annual averages) are of interest the random sampling error tends to ...
Finally, considering the noticeable effect of systematic errors on both cases, it is suggested that flowmeter calibration and regular maintenance is prioritised, although the subsequent economic cost needs to be considered.doi:10.1007/s13202-019-0665-2Mahdi Sadri...
Random assignment to helps you make sure that the treatment groups don’t differ in systematic ways at the start of the experiment, as this can seriously affect (and even invalidate) your work. If you don’t use random assignment, you may not be able to rule out alternative explanations fo...
In the process of measuring the Doppler frequency shift, random and systematic errors will also be generated. • Velocity measurement random error Random errors of the velocity measurement system in pulse radars are generated mainly by thermal noise, multipath, object modulation, and quantization ...
For example, the study of differential item functioning found that there may be systematic differences in item parameters among different groups of respondents and even within groups. Sometimes, such differences indicate that some secondary factors are measured in the items. However, in most cases, ...
