Scheduling (production processes) Scheduling is the process of arranging, controlling and optimizing work and workloads in a production process or manufacturing process. Scheduling is used to allocate plant and machinery resources, plan human resources, plan production processes and purchase materials. It is an important tool for manufacturing and engineering, where it can have a major impact on the productivity of a process. In manufacturing, the purpose of scheduling is to minimize the production time and costs, by telling a p
degree of freedom. n. 1. (General Physics) physics one of the minimum number of parameters necessary to describe a state or property of a system. 2. (General Physics) one of the independent components of motion (translation, vibration, and rotation) of an atom or molecule.
However, this is a partial answer. It explains what degrees of freedom is for many chi-square tests and the numerator degrees of freedom for F tests, but it doesn't do as well with t tests or the denominator degrees of freedom for F tests. At the moment, I'm inclined to define degrees of freedom as a way of keeping score. A data set contains a number of observations, say, n. They constitute n individual pieces of information. These pieces of information can be used either to estimate parameters or variability.
