Schematic representation of measurement categories. Measurement category is a method of classification by the International Electrotechnical Commission (IEC) [1] of live electric circuits used in measurement and testing of installations and equipment, usually in the relation within a building (residential or industrial).
In statistics, a unit is one member of a set of entities being studied. It is the main source for the mathematical abstraction of a "random variable".Common examples of a unit would be a single person, animal, plant, manufactured item, or country that belongs to a larger collection of such entities being studied.
A descriptive statistic is used to summarize the sample data. A test statistic is used in statistical hypothesis testing. A single statistic can be used for multiple purposes – for example, the sample mean can be used to estimate the population mean, to describe a sample data set, or to test a hypothesis.
Class II – Supplies for which allowances are established by tables of organization and equipment, e.g., clothing, weapons, tools, spare parts, vehicles. Class III – Petroleum, oil and lubricants (POL) for all purposes, except for operating aircraft or for use in weapons such as flamethrowers, e.g., gasoline, fuel oil, greases, coal, and coke.
Algorithms of this nature use statistical inference to find the best class for a given instance. Unlike other algorithms, which simply output a "best" class, probabilistic algorithms output a probability of the instance being a member of each of the possible classes. The best class is normally then selected as the one with the highest probability.
When full census data cannot be collected, statisticians collect sample data by developing specific experiment designs and survey samples. Statistics itself also provides tools for prediction and forecasting through statistical models. To use a sample as a guide to an entire population, it is important that it truly represents the overall ...

Categories may be described and named with regard to the type of meanings that they are used to express.
