A basic record number Record numbers is a number that communicates the relative change in cost, amount, or incentive starting with one period then onto the next (1). Value list number = cost of bushel in current period x 100 cost of bushel in base period A record number gives a quantitative depiction of progress over time - what amount of increment? What amount of diminishing? Economic analysts are likewise utilizing file numbers are additionally utilizing list numbers to contrast an examination result and a general standard, to quantify how the speculation, uncommonly in promoting industry, are working.

As the loads don't change period to period (fixed bushel) it very well may be considered to appear solely cost (or amount) change (1). Paasche record -  · Uses amounts from the present time frame, along these lines reflects current purchasing propensities 2.3.2 Limitations Laspeyres record  · It can't be utilized if amounts are hopeless.  · Laspeyres, as time proceeds onward the fixed bin turns out to be less significant. Paasche record  · There can be a mass of factual information prerequisite, as Paasche
