The loss of soil particles and nutrients when the surface soil is carried away by wind, water, or other agents. A measure of the erosive potential of a specific rainfall event. The deviation of a randomly occurring observation from its true or expected value. The difference between experimental plots or experimental units receiving the same treatments. This error comes from the inherent variability which exists in the experimental materials and the variation resulting from any nonuniformity in the physical conduct of the experiment.
Experimental error is always present.
A good experiment is one in which experimental error is kept at the minimum level. Its measurement is essential for use in detecting real differences between treatments. Procedures such as blocking, proper selection of experimental design, measurement techniques, and field plot techniques applied to reduce experimental error. A measure of experimental error. Variance arising from unrecognized or uncontrolled factors in an experiment with which the variance of unrecognized factors is compared in tests of significance.
