    HISTORY OF INDEX NUMBER

    Price index

    A price index (plural: price indices or price indexes) is anormalized average (typically a weightedaverage) of prices for a given

    class of goods or services in a given region, during a given interval of

    time. It is a statistic designed to help to compare how these prices, taken

    as a whole, differ between time periods or geographical locations.

    Price indices have several potential uses. For particularly broad indices,

    the index can be said to measure the economys price level or a cost of

    living. More narrow price indices can help producers with business plansand pricing. Sometimes, they can be useful in helping to guide

    investment.

    Some notable price indices include:

    Consumer price index;

    Producer price index;

    GDP deflator.

    History of early price indices

    No clear consensus has emerges on who created the first price index.

    The earliest reported research in this area came from Welshman Rice

    Vaughan who examined price level change in his 1675 book A

    Discourse of Coin and Coinage. Vaughan wanted to separate the

    inflationary impact of the influx of precious metals brought by Spainfrom the New World from the effect due to currency debasement.

    Vaughan compared labour statutes from his own time to similar statues

    dating back to Edward III. These statutes set wages for certain tasks and

    provided a good record of the change in wage levels. Vaughan reasoned

    that the market for basic labour did not fluctuate much with time and

  • 7/27/2019 Project Add Math 2013 Index Number

    5/23

    that a basic laborers salary would probably buy the same amount of

    goods in different time periods, so that a laborer's salary acted as a

    basket of goods. Vaughan's analysis indicated that price levels in

    England had risen six to eightfold over the preceding century.

    While Vaughan can be considered a forerunner of price index research,

    his analysis did not actually involve calculating an index. In 1707

    Englishman William Fleetwood created perhaps the first true price

    index. An Oxford student asked Fleetwood to help show how prices had

    changed. The student stood to lose his fellowship since a fifteenth

    century stipulation barred students with annual incomes over five

    pounds from receiving a fellowship. Fleetwood, who already had an

    interest in price change, had collected a large amount of price data going

    back hundreds of years. Fleetwood proposed an index consisting of

    averaged price relatives and used his methods to show that the value of

    five pounds had changed greatly over the course of 260 years. He argued

    on behalf of the Oxford students and published his findings

    anonymously in a volume entitled Chronicon Preciosum.

    Part 1(a)The price of goods sold in shop vary from one shop to another. Shoppers

    tend to buy goods which are not only reasonably price but also give

    value for their money.

    You are required to carry out a survey on four different items based on

    the following categories i.e. food,detergent and stationery. The survey

    should be done in three differnt shop.

    (a)Collect picture,newspaper cuttings or photos on item that you have

    chosen. Design a collage to illustrate the chosen item.

    findings.

    Answer:

    Based on the graphical representations that I have constructed in Part 1(c), it is

    shown that there are large and small differences among the prices of items in each

    category between the shops.In the food category, the smallest price difference are

    of those of sugar, while the highest is the price of eggs. Besides food, detergent

    also shows a large price difference between its items. Among them is the price of

    liquid dishwasher and clothes detergent. On the other hand,stationery items doesnt

    have any obvious price difference. The graph also show that most of the items that

    are high priced comes from the Boulevard Supermarket, while the lowest price

    items come from the Discount Store.The graph 1(d) will show the conclusion of

    the difference among the shops based upon the shops grand total.

    FURTHER EXPLAINATION

    Index numbers are being used in many different daily situations, for

    example air pollution index, stock market index, gold index and property

    index.

    Obtain information from the Internet or other reliable sources on the

    importance of two different types of index numbers of your choice.

    Elaborate the use and the importance of these index numbers in daily life

    situations.

    Answer :

    Air Polution Index

    TheAir Pollution Index(API) is used in to measure the quality of air in

    Malaysia, based on several sets of air pollution data.

    A scale is used to show the health classifications used by the Malaysian

    government to determine the API in a specific area:

    0-50 Good

    51-100Moderate 101-200Unhealthy 201-300Very unhealthy >300HazardousIf the API exceeds 500, a state of emergency is declared in the reporting

    area. This usually means that non-essential government services are

    suspended, and all ports in the affected area are closed. There may also

    be a prohibition of commercial and industrial activities which are under

    the private sector in the reporting area excluding the food sector.

    Body Mass Index

  • 7/27/2019 Project Add Math 2013 Index Number

    19/23

    A graph of body mass index is shown above. The dashed lines represent

    subdivisions within a major class. For instance the "Underweight"

    classification is further divided into "severe", "moderate", and "mild"

    subclasses.

    Based onWorld Health Organizationdatahere.The body mass index (BMI), orQuetelet index, is a statistical measure

    of body weight based on a person's weight and height. Though it does

    not actually measure thepercentage of body fat, it is used to estimate a

    healthybody weightbased on a person's height. Due to its ease of

    measurement and calculation, it is the most widely used diagnostic tool

    to identify weight problems within a population, usually whether

    individuals areunderweight,overweightorobese. It was invented

    between 1830 and 1850 by theBelgianpolymathAdolphe

    Queteletduring the course of developing "social physics". Body mass

    index is defined as the individual's body weight divided by the square of

    his or her height. The formulae universally used in medicine produce

    aunit of measureof kg/m2. BMI can also be determined using a BMI

    chart. which displays BMI as a function of weight (horizontal axis) and

    height (vertical axis) using contour lines for different values of BMI or

    colours for different BMI categories.

    Usage

    While the formula previously called the Quetelet Index for BMI dates

    to the 19th century, the new term "body mass index" for the ratio and

    its popularity date to a paper published in the July edition of 1972 in

    theJournal of Chronic Diseases byAncel Keys, which found the BMI

    to be the best proxy for body fat percentage among ratios of weight and

    height; the interest in measuring body fat being due to obesity becoming

    a discernible issue in prosperous Western societies. BMI was explicitlycited by Keys as being appropriate forpopulation studies, and

    inappropriate for individual diagnosis. Nevertheless, due to its

    simplicity, it came to be widely used for individual diagnosis, despite its

    inappropriateness.

    BMI provided a simple numeric measure of a person's "fatness" or

    "thinness", allowing health professionals to discuss over- and under-

    weight problems more objectively with their patients. However, BMI

    has become controversial because many people, including physicians,have come to rely on its apparent numerical authority for medical

    diagnosis, but that was never the BMI's purpose; it is meant to be used

    as a simple means of classifying sedentary (physically inactive)

    individuals with an average body composition. For these individuals, the

    current value settings are as follows: a BMI of 18.5 to 25 may indicate

    http://en.wikipedia.org/wiki/Ancel_Keyshttp://en.wikipedia.org/wiki/Ancel_Keyshttp://en.wikipedia.org/wiki/Ancel_Keyshttp://en.wikipedia.org/wiki/Ancel_Keys
  • 7/27/2019 Project Add Math 2013 Index Number

    21/23

    optimal weight; a BMI lower than 18.5 suggests the person

    isunderweightwhile a number above 25 may indicate the person

    isoverweight; a BMI below 17.5 may indicate the person hasanorexia

    nervosaor a related disorder; a number above 30 suggests the person

    isobese(over 40, morbidly obese).

    For a given height, BMI is proportional to weight. However, for a given

    weight, BMI is inversely proportional to thesquare of the height. So, if

    all body dimensions double, and weight scales naturally with the cube of

    the height, then BMI doubles instead of remaining the same. This results

    in taller people having a reported BMI that is uncharacteristically high

    compared to their actual body fat levels. In comparison, thePonderal

    indexis based on this natural scaling of weight with the third power of

    the height. However, many taller people are not just "scaled up" shortpeople, but tend to have narrower frames in proportion to their height. It

    has been suggested that instead of squaring the body height (as the BMI

    does) or cubing the body height (as thePonderal indexdoes), it would

    be more appropriate to use an exponent of between 2.3 and 2.7.
