a. Describe in briefi. Price Index
ii. Weightageiii. Composite index
PRICE INDEXMeasure of change in a set of prices, consisting of a series of numbers arranged so that a comparison of
the values for any two periods or places will show the change in prices between periods or the
difference in prices between places. Price indexes were first developed to measure changes in the cost
of living in order to determine the wage increases necessary to maintain a constant standard of living.
There are two basic types. Laspeyrestype indexes define a market basket of goods in a base period,
then use the prices for those goods to examine change over space and time. In its simplest form, this is
simply the ratio of what those goods cost today to what they cost in the base period. The two most
familiar indexes of this type are the consumer price index (CPI) and the producer price index (PPI). The
CPI measures changes in retail prices in such component parts as food, clothing, and shelter. The PPI
(formerly called the wholesale price index) measures changes in the prices charged by manufacturers
and wholesalers. Paschaltype indexes define a market basket of goods in the current period, then use
the prices of those goods from past periods. The most familiar index of this type is the GDP deflator,
used in the U.S. in the national income accounting to differentiate amounts in constant dollars from
those in current dollars.
WEIGHTAGEWeightage means preference of one product in comparison to other product. On the other hand we can
say weightage means giving the value of the specific or particular matter or subject higher or lesser thanthat of or in comparison to similar one. The factors of weightage are The more risk, the more weightage,
the longer the period, more the risk, more the uses of Banks facility, less the weightage and last but not
least less the Uses of Banks facility, more the benefit weightage and moral dimension or ethical values.
COMPOSITE INDEXA grouping of equities, indexes or other factors combined in a standardized way, providing a useful
statistical measure of overall market or sector performance over time. Usually, a composite index has a
large number of factors which are averaged together to form a product representative of an overall
market or sector. For example, the Nasdaq Composite index is a market capitalizationweighted
grouping of approximately 5,000 stocks listed on the Nasdaq market. These indexes are useful tools for
measuring and tracking price level changes to an entire stock market or sector. Therefore, they provide
a useful benchmark against which to measure an investor's portfolio. The goal of a well diversified
portfolio is usually to outperform the main composite indexes.

Comment :
My family used up money on education as education is important in our life. My family often buys new
books every weeks as for us reading is the key to success in life no matter how much the cost of the
book. Instead, my family used least money on recreation due to busy of works and studies.

d. Make a conclusion about your familys expenditure based on your findings.From the findings, I can see the increasing of my familys expenditure especially on recreation.
When all of us are bigger, more pressure on us as more thing have to be done. So, spending time
with family for recreation will be the best solution for us to handle the pressure.

Your family is planning to buy a new television set.
a. You have conducted a survey on the price of the television for two different brands from threedifferent shops. You would like to make a comparison between two modes of payment, namely, cash
payment and payment by installment.
Table 4(a) shows the prices of televisions by cash payment in three different shops whereas Table
4(b) shows the prices of televisions by installment. Complete Table 4(a) and 4(b) using the data you
obtained.

b. Determine the brand and size of the television that you have decided to buy. Give your reasons basedon the findings from part (a) above.
I have decided to buy television from brand A with the size of 40 inch. The reasons of my choice are
because the prices for brand A are more cheaper than brand B paid by cash nor installment. We can
see it from my findings as the measure of dispersion for brand A is lower than brand B. The lower
the measure of dispersion from the mean and standard deviation from zero, the lower the prices of
the televisions. So, I strongly choose television from brand A with the size 40 inch.
c. The Ministry of Domestic Trade and Consumer Affairs wishes to present the Fair Prices Shop Awardfor one of the above shops. If you are one of the panels for this award, determine the shops that
deserve the award. Do you consider the value of mean and the value of standard deviation in making
your decision? Give your justification.
In my opinion, the Fair Prices Shop Award should be given to Shop B. As one of the panels, I consider
the value of mean and the value of standard deviation in making my decision as I think it is
important for us to know the unit of dispersion for each shop. Here are the brief reason why I used
the method. The mean of set of prices the sum of the prices divided by the number of prices. Along
with the median and the mode, the mean is just one measure of the central tendency of a set of
scores, but the mean is by far the most common and the most useful. Although the mean tells us
where the center of a set of scores is, it does not tell us how variable those scores are. So in
addition to a measure of central tendency, we need a measure of variability. Standard deviation
measures how spread out the values in a data set are around the mean. More precisely, it is a
measure of the average distance between the values of the data in the set and the mean. If the data
values are all similar, then the standard deviation will be low (closer to zero). If the data values are
highly variable, then the standard variation is high (further from zero). So, from my calculation and
findings it is clearly shown that Shop B have a lower measure of dispersion means the prices is
maintain at one stage. So, in my opinion I will choose Shop B to receive the Fair Prices Shop Award.

REFLECTION
While doing this project, I have spent countless hours doing this
project. I realized that this subject is compulsory to me. Without it, Icant fulfill my big dreams and wishes.
I used to
Hate Additional Mathematics
It always make me wonder why this subject is so difficult
It always an absolute obstacle for me
Throughout day and night
I sacrificed my precious time to have fun
From
Monday, Tuesday, Wednesday, Thursday, Friday
And
even the weekend that I always looking forward to
From now on, I will do my best on every second
That I will learn Additional Mathematics full of effort!!!
And with the help of Madam Azzah
