Systematic error is a series of errors in accuracy that are consistent in a certain direction, or over time. In general, systematic errors cause a bias in ...

With the usage of micropipettes in the life science laboratory, various pipette and pipetting errors have been linked. Users familiar with such micropipette issues can assist users to reduce further ...

When gathering a measurement using a spectroscopy instrument, the user wants to be confident in the result. Whether the technique is OES, XRF, or LIBS, or if thickness or composition are measured, the ...

Developing a method is an important part of planning an investigation. In an experiment, evaluate the validity of the steps leading up to the conclusion for it to be valid. Random and systematic ...

Random errors are errors made by the person carrying out the measuring, and are usually down to timing incorrectly, or reading the instrument incorrectly. It is important to try to reduce or limit the ...

Rachel Martins explains how she introduced random error into her lab simulations when teaching online physics, to better replicate real-world experiments for her ...
