Statistical Terms Glossary

Age-standardized prevalence of raised blood glucose/diabetes among persons aged 18+ years or on medication for raised blood glucose (defined as fasting plasma glucose value ≥ 7.0 mmol/L (126 mg/dL) or on medication for raised blood glucose among adults aged 18+ years).

Apart from its ordinary significance this term is used in the following special sense. The coefficients of a linear function of the values of the sample units used to estimate population, stratum, or higher stage unit totals are called raising, multiplying, weighting or inflation factors of the corresponding sample units.

See revenue anticipation note.

The word is used in senses ranging from “non-deterministic” (as in random process) to “purely by chance, independently of other events” ( as in “test of randomness”).

The most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible.

If a magnitude consists of a number of parts compounded in some way, e.g. by addition or multiplication, any such part as is a variate is a random component of the magnitude.

This expression is sometimes wrongly used for a probability distribution. It is also sometimes employed to denote a distribution of probability which is uniform in the range concerned, i.e. a rectangular distribution. It seems better to avoid the term altogether, or, in such expressions as “points randomly distributed over an area” to specify clearly the law of distribution involved.

An error, that is to say, a deviation of an observed from a true value, which behaves like a variate in the sense that any particular value occurs as though chosen at random from a probability distribution of such errors.

Uses imputation classes to constrain the random selection of the donor record to a set considered to have some similarity to the record requiring imputation.

For each failed edit record, one passed edit record is selected at random from the set of all passed edit records, and its reported value for the item in question is imputed for the failed edit record.

Any method of selection of a sample based on the theory of probability; at any stage of the operation of selection the probability of any set of units being selected must be known. It is the only general method known which can provide a measure of precision of the estimate. Sometimes the term random sampling is used in the sense of probability sampling.

Also referred to as ADSL2 or G.DMT.bis. It optionally extends the capability of basic ADSL in data rates to 12 Mbit/s downstream and 3.5 Mbit/s upstream (with a mandatory capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 Kbit/s upstream). Actual speeds may reduce depending on line quality - usually the most significant factor in line quality is the distance from the DSLAM to the customer's equipment. reach extended : Increases the range of the DSL service enabling the link to work at a distance of 7 kilometers, or 23000 f.

Range management is the use of grazing land to ensure consistent livestock production and, at the same time, conserve range resources

A form of sexual assault, involving illegal sexual intercourse with a person against that person’s will/consent. Typically involves sexual penetration without consent including sexual penetration obtained by force, threat or incapacitation, or sexual penetration of someone who is unable to give consent, such as a younger child or incompetent person (National Centre on Sexual Behaviour of Youth, 2003). However, the most commonly used definition of rape is the imposition of sexual assault on someone against his will, through the use of violence, force, threat to harm or other forms of coercion, or in the case of the victim's incapacity to refuse if under the influence of alcohol or drugs. When an effort is placed to rape someone without penetration, this is called an attempted rape. Rape is a judicial definition that differs according to the laws in different countries.

When an effort is placed to rape someone without penetration, this is called an attempted rape.

Complex of beliefs that encourages male sexual aggression and supports violence against women.

RAAKS is a methodology developed at Wageningen Agricultural University during the 1990s. It combines elements of PRA and institutional analysis to create a framework for participatory action research to understand and improve agricultural knowledge systems, which are broadly defined to include all those generating, transmitting or using knowledge: researchers, policy-makers, extensionists, farmers etc.

Rare species ate taxa with small world populations that, though not at present endangered or vulnerable, are at risk. These taxa are localized within restricted geographical areas or habitats or thinly scattered over a more extensive range

The occurrence of events over a specific interval. Also refers to the measure of the frequency of a phenomenon of interest.

Change from one type of interest rate to another.
