| random error |
Error that occurs due to natural variation in the process. Note: Random error is typically assumed to be normally distributed with zero mean and a constant variance. Note: Random error is also called experimental error.

A schedule for allocating treatment material and for conducting treatment combinations in a DOE such that the conditions in one run neither depend on the conditions of the previous run nor predict the conditions in the subsequent runs. Note: The importance of randomization cannot be over stressed. Randomization is necessary for conclusions drawn from the experiment to be correct, unambiguous and defensible.

Random error is the irreproducibility in making replicate measurements and affects the precision of a result. The distribution of random errors follows a Gaussian-shape "bell" curve. The precision is described by statistical methods such as a standard deviation or confidence limit.

Study participants are usually assigned to groups in such a way that each participant has an equal chance of being assigned to each treatment (or control) group. Since randomization ensures that no specific criteria are used to assign any patients to a particular group, all the groups will be equally comparable.

is filled with M_ realisations of an uniformly(-1/2, 1/2) distributed random variable. The same value of this realisation is later used in every physical point x.
