An index number is a statistic indicating the relative change occurring in the price or value of a commodity, share price or in a general economic variable e.g. retail price increases, with reference to a previous base period conventionally given the number 100.
A numerical , usually indicating, by comparison with a base value of 100, the size of the index relative to a base year or other benchmark for comparison. Thus, for example, a CPI of 115 in 2004 with a base year of 1999 means that the index has risen 15% from 1999 to 2004.
a weighted average of a number of statistical observations of some economic attribute, as a percentage of a similar weighted average calculated for the attribute at an earlier, or base, period; typical economic attributes for which index numbers are calculated are prices and production, the most familiar being the cost-of-living index. weighted average meteorology
The term "index number" has been applied to a series of somewhat similar devices employed in the analysis of statistical time series. In its simplest expression an index number may take the form of converting a time series (eg. Of apple consumption) into a series of figures where consumption is expressed as 100 for some base period (eg. The average of the 5 years before World War II). After this base period has been designated the figures for other years are expressed as a ratio to the figures in the base period. Similarly, one can construct index numbers for the level of consumer prices, agricultural production, etc. This involves 1. Choosing a base period, and 2. Choosing weights for converting dissimilar products (eg. Apples and meat) to a common denominator. In the case of the consumer price index this problem is usually solved by taking a basket of goods, valuing it at the retail price during some base period and working out the percentage increase or decrease in the subsequent period.
a ratio or number that indicates the potential of a particular market; generally, a percentage above or below the national average. The measure of difference, usually expressed as a percent, between one variable of a specific kind to another variable of the same kind, i.e., a number indicating the relationship between a particular factor and a base (which has a value of 100). For marketing use, the ratio helps to show a market's potential. Example: with data in hand on “favorite brand” of domestic beer, broken down by age groups, we see an index number of 143 under Budweiser for individuals 25-34, the interpretation is that individuals 25-34 are 43 percent more likely than the rest of the total adult population to have Budweiser at their favorite beer (an index number of 85 would mean they are 15 percent less likely…).
A ratio that shows percentage change over time. Usually a benchmark value is set at 100, and the value before and after that year is calculated as a percentage of the baseline. The Consumer Price Index is an example of an index number.
a number or ratio (a value on a scale of measurement) derived from a series of observed facts; can reveal relative changes as a function of time
a derived quantity that describes the ratio of a quantity and its value at a base period (or its values at a standard)
a number used by the court to identify a case
A single number which gives the average value of a set of related items, share prices for example, expressed as a percentage of their average value at a base period (e.g. 30 December 1983 for the FTSE 100).
Case number used to identify and requisition foreclosure file of the case for examination. JUDGMENT: A decree of a court stating that one individual is indebted to another and fixing the amount of the indebtedness.
A number that measures the difference in the level of price, volume, or value of a set or 'basket' of related items between a selected base period and the current period.
A number set equal to 100 in the base year, and used to measure changes in prices or quantities.
Form of converting a chronological or synchronous series into readily comparable magnitudes by assigning the value of 100 to the first or most expressive datum and expressing the others in proportion to that baseline.
A term used by card-counters to identify the count. For instance, going by the Hi-Lo count, the index number for standing on a hard 16 when the dealer has a 10 would be 0.
a number issued by the county clerk, which is used to identify a case - in civil matters there is usually a fee
A case number assigned as part of the pre foreclosure or foreclosure process, which is used to reference a particular legal action or case.
The unique number assigned by the County Clerk’s office to every action or proceeding commenced within the New York State Supreme Court. The number is used to identify a case in that court, and should be indicated on all papers served on the parties and filed with the court. The number is either: (a) purchased; or (b) obtained after a Poor Person Application is filed and approved by the court.
a number issued by the county clerk, which is used to identify a case - in civil court there is a charge of $45.00 infant's compromise: a civil proceeding or motion for obtaining court approval of the settlement of an infant's claim
Index number, in econometrics, is a figure reflecting value or quantity as compared with a standard or base value. The base usually equals 100 and the index number is usually expressed as a percentage. For example, if a commodity cost twice as much in 1970 as it did in 1960, its index number would be 200 relative to 1960.
