History Of Index NumberIndex numbers are meant to study the change in the effects of such factors

which cannot be measured directly. According to Bowley, Index numbers are used tomeasure the changes in some quantity which we cannot observe directly. Forexample, changes in business activity in a country are not capable of directmeasurement but it is possible to study relative changes in business activity bystudying the variations in the values of some such factors which affect businessactivity, and which are capable of direct measurement.

Index numbers are commonly used statistical device for measuring thecombined fluctuations in a group related variables. If we wish to compare the pricelevel of consumer items today with that prevalent ten years ago, we are not

interested in comparing the prices of only one item, but in comparing some sort ofaverage price levels. We may wish to compare the present agricultural production orindustrial production with that at the time of independence. Here again, we have to


4/30

consider all items of production and each item may have undergone a differentfractional increase (or even a decrease). How do we obtain a composite measure? Thiscomposite measure is provided by index numbers which may be defined as a devicefor combining the variations that have come in group of related variables over a

period of time, with a view to obtain a figure that represents the net result of thechange in the constitute variables.

Index numbers may be classified in terms of the variables that they areintended to measure. In business, different groups of variables in the measurement ofwhich index number techniques are commonly used are (i) price, (ii) quantity, (iii)value and (iv) business activity. Thus, we have index of wholesale prices, index ofconsumer prices, index of industrial output, index of value of exports and index ofbusiness activity, etc. Here we shall be mainly interested in index numbers of pricesshowing changes with respect to time, although methods described can be applied toother cases. In general, the present level of prices is compared with the level of pricesin the past. Thepresent period is called the current period and some period in the

past is called the base period.

Index number.Index numbers are statistical measures designed to show changes in a

variable or group of related variables with respect to time, geographic location orother characteristics such as income, profession, etc. A collection of index numbers fordifferent years, locations, etc., is sometimes called an index series.

Simple Index numberA simple index number is a number that measures a relative change in a

single variable with respect to a base.

Composite index NumberA composite index number is a number that measures an average relative

changes in a group of relative variables with respect to a base.

Part 1The prices of goods sold in shops vary from one shop to

another.

Answer:


14/30

Based on the graphical representations that I have constructed in Part 1(c), it isshown that there are large and small differences among the prices of items ineach category between the shops.In the food category, the smallest pricedifference are of those of sugar, while the highest is the price of eggs. Besides

food,clothes detergent,Dynamo also shows a large price difference On theother hand,stationery items doesnt have any obvious price difference. Thegraph also show that most of the items that are high priced comes from theAdil mart , while the lowest price items come from the Giant supermarket.Thegraph 1(d) will show the conclusion of the difference among the shops basedupon the shops grand total.

Graph 1(d)

Question.

(e) Identify an item that has a large price difference among the shops.Calculate the mean and standard deviation of that particular item.Hence, suggest and discuss possible reasons for the price difference.


15/30

Answer:

Dynamo :

Mean==17.71

Standard deviation= ()/N ( )

= - (17.71)

=0.97 The large price difference of clothes detergent among the shops maybebecause of the standard of the shop.A high standard shop or supermarket, theitems sold intend to be much more expensive than a regular shop orsupermarket .Also, the price difference of the items may also due to the quality

of the item present. A better quality means a higher price.

Further Exploration

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

example air pollution index, stock market index, gold index andproperty index.Obtain information from the internet or other reliable sources onthe importance of two different types of index number of yourchoice.Elaborate the use and the importance of these index numbers indaily life.

Air Pollution Index

Air pollution is the introduction ofchemicals, particulate matter,or biological materials that cause harm or discomfort to humans orother living organisms, or damages the natural environment intothe atmosphere.

The atmosphere is a complex dynamic natural gaseous system thatis essential to support life on planet Earth. Stratosphericozonedepletion due to air pollution has long been recognized as a threatto human health as well as to the Earth's ecosystems.

The Air Quality Index (AQI) (also known as the Air PollutionIndex (API) or Pollutant Standard Index (PSI) is a number used bygovernment agencies to characterize the quality of the air at agiven location. As the AQI increases, an increasingly largepercentage of the population is likely to experience increasinglysevere adverse health effects. To compute the AQI requires an airpollutant concentration from a monitor or model. The function usedto convert from air pollutant concentration to AQI varies by

pollutant, and is different in different countries. Air quality indexvalues are divided into ranges, and each range is assigned a

descriptor and a color code. Standardized public health advisoriesare associated with each AQI range. An agency might alsoencourage members of the public to take public transportation or

work from home when AQI levels are high.

Limitations of the AQI

Most air contaminants do not have an associated AQI. Manycountries monitor ground-level ozone, particulates, sulphurdioxide, carbon monoxide and nitrogen dioxide and calculate airquality indices for these pollutants.

Causes of Poor Air QualityThe AQI can worsen (go up) due to lack of dilution of air emissionsby fresh air. Stagnant air, often caused byan anticyclone or temperature inversion, or other lackofwinds lets air pollution remain in a local area.

Indices by locationSouth Korea

The Ministry of Environment of South Korea uses theComprehensice Air-quality Index (CAI) to describe the ambient airquality based on health risk of air pollution. The index aims to helpthe public easily understand air quality level and protect the healthof people from air pollution. - The CAI has values of 0 through 500,which are divided into six categories. The higher the CAI value, thegreater the level of air pollution. - Of values of the five airpollutants, the highest is the CAI value.

Malaysia

The air quality in Malaysia is reported as the API or Air PollutionIndex. Four of the index's pollutant components (i.e., carbonmonoxide, ozone, nitrogen dioxide and sulfur dioxide) are reportedin PM10 particulate matter is reported in g/m.

Unlike the American AQI, the index number can exceed 500. Above500, a state of emergency is declared in the reporting area.Usually, this means that non-essential government services aresuspended, and all ports in the affected area closed. There mayalso be a prohibition on private sector commercial and industrialactivities in the reporting area excluding the food sector.

Stock Market Index

A comparison of three major U.S. stock indices: theNASDAQComposite, Dow Jones Industrial Average, andS&P 500. All threehave the same height at March 2007. Notice the large dot-com spike on the NASDAQ, a result of the large number of tech.companies on that index.

A stock market index is a method of measuring a section of

the stock market. Many indices are cited by news or financialservices firms and are used as benchmarks, to measure theperformance ofportfolios such as mutual funds.

Types of indicesStock market indices may be classed in many ways. A 'world' or'global' stock market index includes (typically large) companieswithout regard for where they are domiciled or traded. Twoexamples are MSCI World and S&P Global 100.

Anational

index represents the performance of the stock market ofa given nationand by proxy, reflects investor sentiment on thestate of its economy. The most regularly quoted market indices arenational indices composed of the stocks of large companies listedon a nation's largest stock exchanges, such as the American S&P500, the Japanese Nikkei 225, and the British FTSE 100.

The concept may be extended well beyond an exchange. The DowJones Total Stock Market Index, as its name implies, represents thestocks of nearly every publicly traded company in the UnitedStates, including all U.S. stocks traded on the New York StockExchange (but not ADRs) and most traded on

the NASDAQ and American Stock Exchange. Russell InvestmentGroup added to the family of indices by launching the RussellGlobal Index.

More specialized indices exist tracking the performance of specificsectors of the market. The Morgan Stanley Biotech Index, forexample, consists of 36 American firms inthe biotechnology industry. Other indices may track companies of acertain size, a certain type of management, or even morespecialized criteria one index published by Linux WeeklyNews tracks stocks of companies that sell products and servicesbased on the Linux operating environment.

Index versionsSome indices, such as the S&P 500, have multiple versions.[1] Theseversions can differ based on how the index componentsare weighted and on how dividends are accounted for. For example,there are three versions of the S&P 500 index: price return, whichonly considers the price of the components, total return, whichaccounts for dividend reinvestment, and net total return, whichaccounts for dividend reinvestment after the deduction of awithholding tax. As another example, the Wilshire4500 and Wilshire 5000 indices have five versions each: fullcapitalization total return, full capitalization price, float-adjustedtotal return, float-adjusted price, and equal weight. The differencebetween the full capitalization, float-adjusted, and equal weightversions is in how index components are weighted.

Uses and importance of air pollution index and stock market index

As everyone can see,the air pollution index is use by thegovernment to measure the air quality index and to detect anypollutants in our countrys air.This is to ensure the air is clean andsafe for us to inhale.Besides that,an early warning can be given tous if the air pollution is to high for us to get out of our homes. Thiswarning is given based upon readings and interpretations of the airpollution index.As for the stock market index, it is mainly for the businessentrepreneurs. This type of index is used to determine the outcome

of a stock market and also the conclusion of a stock market. The
