    OBJECTIVESWe students taking Additional Mathematics are required to carry out a project work while

    we are in Form 5. This year the Curriculum Development Division, Ministry of Education hasprepared four tasks for us. We are to choose and complete only ONE task based on our area of

    interest. This project can be done in groups or individually, but each of us are expected to

    submit an individually written report. Upon completion of the Additional Mathematics Project

    Work, we are to gain valuable experiences and able to:

    Apply and adapt a variety of problem solving strategies to solve routine and non-routine problems;

    Experience classroom environments which are challenging, interesting and meaningfuland hence improve their thinking skills.

    Experience classroom environments where knowledge and skills are applied inmeaningful ways in solving real-life problems

    Experience classroom environments where expressing ones mathematicalthinking,reasoning and communication are highly encouraged and expected

    Experience classroom environments that stimulates and enhances effective learning. Acquire effective mathematical communication through oral and writing,and to use

    the language of mathematics to express mathematical ideas correctly and precisely

    Enhance acquisition of mathematical knowledge and skills through problem-solving inways that increase interest and confidence

    Prepare ourselves for the demand of our future undertakings and in workplace Realise that mathematics is an important and powerful tool in solving real-life

    problems and hence develop positive attitude towards mathematics.

    Train ourselves not only to be independent learners but also to collaborate, tocooperate, and to share knowledge in an engaging and healthy environment

    FOREWARDFirst of all, I would like to say Alhamdulillah, for giving me the strength and health to do this

    project work. Not forgotten my parents for providing everything, such as money, to buy anything

    that are related to this project work and their advice, which is the most needed for this project.

    Internet, books, computers, and etc. They also supported me and encouraged me to complete

    this task so that I will not procrastinate in doing it. Then I would like to thank my teacher, En. Nor

    Azizi Bin Fain for guiding me and my friends throughout this project. We had some difficulties in

    doing this task, but she taught us patiently until we knew what to do. She tried and tried to teach

    us until we understand what we supposed to do with the project work. Last but not least, my

    friends who were doing this project with me and sharing our ideas. They were helpful that when

    we combined and discussed together, we had this task done.

    Index 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 to measure the changes in some

    quantity which we cannot observe directly. For example, changes in business activity in a country

    are not capable of direct measurement but it is possible to study relative changes in business

    activity by studying the variations in the values of some such factors which affect business activity,

    and which are capable of direct measurement.

    Index numbers are commonly used statistical device for measuring the combined

    fluctuations in a group related variables. If we wish to compare the price level 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 of average price levels. We may wish to compare the present

    agricultural production or industrial production with that at the time of independence. Here again,

    we have to consider all items of production and each item may have undergone a different

    fractional increase (or even a decrease). How do we obtain a composite measure? This composite

    measure is provided by index numbers which may be defined as a device for 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 the change in the constitute variables.

  • 7/23/2019 Project Work Add Math 2013 Pahang



    Index numbers may be classified in terms of the variables that they are intended to

    measure. In business, different groups of variables in the measurement of which 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 of consumer prices, index of industrial output,

    index of value of exports and index of business activity, etc. Here we shall be mainly interested

    in index numbers of prices showing changes with respect to time, although methods described

    can be applied to other cases. In general, the present level of prices is compared with the level

    of prices in the past. Thepresent period is called the current period and some period in the past

    is called the base period.

    Index Numbers:

    Index numbers are statistical measures designed to show changes in a variable or group

    of related variables with respect to time, geographic location or other characteristics such as

    income, profession, etc. A collection of index numbers for different years, locations, etc., is

    sometimes called an index series.

    Simple Index Number:

    A simple index number is a number that measures a relative change in a single variable

    with respect to a base.

    Composite Index Number:

    A 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 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: food, detergent and stationery. The survey should be done in three different shop.

    Part 1(a)

    Collect picture, newspaper cuttings or photos on item that you have chosen. Design a collage to

    illustrate the chosen item.

    Part 1 (d):

    Based on the graphical representations that you have constructed in part 1(c), interpret,discuss and draw consclusion. Comment on your findings.

    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.

    Standard deviation = ()2= 1921+20.53 (1216 )2=1222.253 (1216 )2= 0.8498

    Reason of difference in price :

    Bulk buying from the retailer gives the lower cost resulted in lower relling price. Hypermarket own brands are much cheaper than the expansive brand-dont involve in

    advertiving resulted in lower selling price

    Sales and discount offer by the supermarket.

    PART 3In order to upgrade the security, my school has decided to install closed-circuit TV (CCTV).

    Part 3(a)

    Suggest a suitable number of cameras to be installed and their placement. Give your reasons.

    Illustrate with a plan.

    I suggest 4 cameras to be installed at my school. The cameras will be installed at the staff rooms

    and the office. This action will be done to avoid any robbery case from happen.

    Part 3(b)

    Find out the cost of installation of the CCTV.

    A set of CCTV with 4 cameras : RM2100

  • 7/23/2019 Project Work Add Math 2013 Pahang



    Part 3(c)

    If your class intends to sponsor 10% of the cost, how many packets of nasi lemak must yourclass sell?

    10% X RM2100 = RM210

    Cost for a packet of nasi lemak =RM13.22

    10 = RM1.40

    Selling price = RM2.10

    Profit = RM2.10 RM1.40

    = RM0.70

    Packets of nasi lemak must be sell =RM210RM0.70

    = 300 packets

    Part 3(d)

    Can your class achieve the 10% target? Do you think your class should carry out a different

    project instead?

    Yes because many visitors from Pekan will come and visit our school during the

    carnival.This phenomenon will increase the selling of our nasi lemak. Last year, we had sold

    about 400 packets of nasi lemak. So, this year our target is 600 packets of nasi lemak will

    besold. From the selling, we can sponsor 10% for the cost of installation of the CCTV andwe will

    get profit of about RM210. I think my class should not carry out different projectas we can get alot of profit from the selling of nasi lemak. We need to focus on sellingnasi lemak only so we

    can achieve our target. Great efforts will led to great outcomes

    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 number of your choice. Elaborate the use and the importance of these

    index numbers in daily life.

    Air Pollution Index

    Air pollution is the introduction ofchemicals, particulate matter, or biological

    materials that cause harm or discomfort to humans or other living organisms, or damages

    the natural environment into the atmosphere.

    The atmosphere is a complex dynamic natural gaseous system that is essential to

    support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been

    recognized as a threat to human health as well as to the Earth's ecosystems.

    The Air Quality Index (AQI) (also known as the Air Pollution Index (API) or Pollutant

    Standard Index (PSI) is a number used by government agencies to characterize the quality of

    the air at a given location. As the AQI increases, an increasingly large percentage of the

    population is l ikely to experience increasingly severe adverse health effects. To compute the

    AQI requires an air pollutant concentration from a monitor or model. The function used to

    convert from air pollutant concentration to AQI varies by pollutant, and is different in different

    countries. Air quality index values are divided into ranges, and each range is ass igned a

    descriptor and a color code. Standardized public health advisories are associated with each AQI

    range. An agency might also encourage members of the public to take public transportation or

    work from home when AQI levels are high.
  • 7/23/2019 Project Work Add Math 2013 Pahang



    Limitations of the AQI

    Most air contaminants do not have an associated AQI. Many countries monitor ground-

    level ozone, particulates, sulphur dioxide, carbon monoxide and nitrogen dioxide and calculate

    air quality indices for these pollutants.

    Causes of Poor Air Quality

    The AQI can worsen (go up) due to lack of dilution of air emissions by fresh air. Stagnant air,

    often caused by an anticyclone or temperature inversion, or other lack ofwinds lets air

    pollution remain in a local area.

    Indices by location

    South Korea

    The Ministry of Environment of South Korea uses the Comprehensice Air-quality Index

    (CAI) to describe the ambient air quality based on health risk of air pollution. The index aims to

    help the public easily understand air quality level and protect the health of people from air

    pollution. - The CAI has values of 0 through 500, which are divided into six categories. The

    higher the CAI value, the greater the level of air pollution. - Of values of the five air pollutants,

    the highest is the CAI value.
  • 7/23/2019 Project Work Add Math 2013 Pahang



    CAI Description Health Implications

    0-50 Good A level that will not impact patients suffering from diseases relatedto air pollution.

    51-100 ModerateA level which may have a meager impact on patients in case of

    chronic exposure.

    101-150Unhealthy for

    sensitive groups

    A level that may have harmful impacts on patients and members of

    sensitive groups.

    151-250 Unhealthy

    A level that may have harmful impacts on patients and members of

    sensitive groups (children, aged or weak people), and also cause the

    general public unpleasant feelings.

    251-350 Very unhealthyA level which may have a serious impact on patients and members o

    sensitive groups in case of acute exposure.

    351-500 Hazardous

    A level which may need to take emergency measures for patients

    and members of sensitive groups and have harmful impacts on the

    general public.

    The air quality in Malaysia is reported as the API or Air Pollution Index. Four of the

    index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur

    dioxide) are reported in PM10particulate matter is reported in g/m.

    Unlike the American AQI, the index number can exceed 500. Above 500, a state of

    emergency is declared in the reporting area. Usually, this means that non-essential government

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

    prohibition on private sector commercial and industrial activities in the reporting area excluding

    the food sector.

    Stock Market Index

    A comparison of three major U.S. stock indices: the NASDAQ Composite, Dow Jones

    Industrial Average, and S&P 500. All three have 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


    A stock market index is a method of measuring a section of the stock market. Many

    indices are cited by news or financial services firms and are used as benchmarks, to measure

    the performance ofportfolios such as mutual funds.

    Types of indices

    Stock market indices may be classed in many ways. A 'world' or 'global' stock market

    index includes (typically large) companies without regard for where they are domiciled or

    traded. Two examples are MSCI World and S&P Global 100.

    A national index represents the performance of the stock market of a given nationand

    by proxy, reflects investor sentiment on the state of its economy. The most regularly quoted

    market indices are national indices composed of the stocks of large companies listed on a

    nation's largest stock exchanges, such as the American S&P 500, the Japanese Nikkei 225, and

    the British FTSE 100.
  • 7/23/2019 Project Work Add Math 2013 Pahang



    The concept may be extended well beyond an exchange. The Dow Jones Total Stock

    Market Index, as its name implies, represents the stocks of nearly every publicly traded

    company in the United States, including all U.S. stocks traded on the New York Stock

    Exchange (but not ADRs) and most traded on the NASDAQand American Stock

    Exchange. Russell Investment Group added to the family of indices by launching the Russell

    Global Index.

    More specialised indices exist tracking the performance of specific s ectors of the

    market. The Morgan Stanley Biotech Index, for example, consists of 36 American firms in

    the biotechnology industry. Other indices may track companies of a certain size, a certain type

    of management, or even more specialized criteria one index published by Linux Weekly

    News tracks stocks of companies that sell products and services based on the Linux operating


    Index versions

    Some indices, such as the S&P 500, have multiple versions.[1]These versions can differ

    based on how the index components are weighted and on how dividends are accounted for.

    For example, there are three versions of the S&P 500 index: price return, which only considers

    the price of the components, total return, which accounts for dividend reinvestment, and net

    total return, which accounts for dividend reinvestment after the deduction of a withholding

    tax. As another example, the Wilshire 4500 and Wilshire 5000 indices have five versions each:full capitalization total return, full capitalization price, float-adjusted total return, float-adjusted

    price, and equal weight. The difference between the full capitalization, float-adjusted, and

    equal weight versions 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 the government to measure the air

    quality index and to detect any pollutants in our countrys air.This is to ensure the air is clean

    and safe for us to inhale.Besides that,an early warning can be given to us if the air pollution is tohigh for us to get out of our homes. This warning is given based upon readings and

    interpretations of the air pollution index.

    As for the stock market index, it is mainly for the business entrepreneurs. This type of

    index is used to determine the outcome of a stock market and also the conclusion of a stock

    market. The stock market index is important because a countrys economical state sometimes

    depend on it.

    After doing research, answering questions, drawing graphs and some problem solving, I saw

    that the usage of index number is important in daily life. It is not just widely used in markets butalso in interpreting the condition of the surrounding like the air or the water. Especially in

    conducting an air-pollution survey. In conclusion, statistics is a daily life essecities. Without it,

    surveys cant be conducted, the stock market cant be interpret and many more. So, we should

    be thankful of the people who contribute in the idea of statistics.
