## Index numbers are used to measure changes in the value of money. A study of the rise or fall in the value of money is essential for determining the direction of production and employment to facilitate future payments and to know changes in the real income of different groups of people at different places and times.

An index number is an economic data figure reflecting price or quantity compared with a standard or base value. The base usually equals 100 and the index number is usually expressed as 100 times the ratio to the base value. For example, if a commodity costs twice as much in 1970 as it did in 1960, index number. n. A number indicating change in magnitude, as of price, wage, employment, or production shifts, relative to the magnitude at a specified point usually taken as 100. The National Council of Teachers (USA, 1989) identified five components that characterise number sense: number meaning, number relationships, number magnitude, operations involving numbers and referents for numbers and quantities. Most European systems of number words are irregular up to 100. For example in French, 92 is said as "four twenty twelve," corresponding to 4*20 + 12. The more complicated the number word system is, the harder it is for children to learn the counting sequence. an index based on the geometric mean formula will be closer to a COLI than will a Laspeyres index. 3 For a review of index number formulas, their properties, and their re-lationship to economic theory, see W. E. Diewert, “Index numbers,” in J. Eatwell, M. Malgate, and P. Newman eds., The new Palgrave: a dictionary Comorbidity is most often defined in relation to a specific index condition, 18 as in the seminal definition of Feinstein: “Any distinct additional entity that has existed or may occur during the clinical course of a patient who has the index disease under study.” 12 The question of which condition should be designated the index and which A master patient index (MPI) facilitates the identification and linkage of patients' clinical information within a particular institution. The term “enterprise master patient index” (EMPI) is sometimes used to distinguish between an index that serves a single institution (i.e., MPI) and one that contains data from multiple institutions (EMPI).
