Chapter 3


3.0 Introduction

The aims of this survey are to happen the correlativity between the economic variables and impact towards the consumer monetary value index. Specifically, this survey is determined which variable is have a immense impact towards the motion of the CPI. Therefore by making this research we can precisely acquire the true information on the motion of the consumer monetary value index instead than do premise based on the ain political orientation. To accomplish the aim of survey, several trial have been use to acquire the consequence of the variable. Example of the trial that wants to be done is T-Test, F aa‚¬ ” Test and Multiple Regressions. The trial has been taking because of it will give a clear and crystalline position on the consequence and its unsophisticated compared to others prove that more complicated. This trial besides have been supported by the hypothesis based on the apprehension on the issued that been research or discuss. The hypothesis is the early premise on the consequence that will go on at the terminal of the survey.


Data concerning on the historical of CPI and the economic variables were gathered to see whether there are any correlativity between the dependant and all those independent variables.

The secondary informations will be collected from the past recent diary sing this survey. The survey or research have been develop by the foreign people or state, but the variable is non the same but still similar. The diary that been used is merely for support the consumer monetary value index state of affairs.

3.2 Sampling Frame

To procure an acceptable consequence, this survey decided to utilize 5 economic variables from others economic variables and the information is collected for 5 old ages and in monthly footing.

3.3 Beginnings OF DATA

The information on the dependent variables CPI was collected from the Malaysian Department of Statistic and the informations are updated until December 2010 which is on the current updated. The information is in Malayan Ringgit ( RM ) . Following for the independent variables the informations are been collected from the DataStream which is for Inflation Rate in per centum ( % ) , Exchange rate in Malayan ringgit ( RM ) , Money Supply in Malaysian Ringgit ( RM ) , and in conclusion for the palm oil is still in the Malayan Ringgit ( RM ) . The informations have been collected from January 2005 until December 2010 and by utilizing monthly informations footing.


The variables used in this survey can be categorized into two chief types which are the dependant and the independent variables.

3.4.1 Dependent Variables

The dependant variable for this survey is the Consumer Price Index which will be measured in footings of mean general degree of monetary value that been group under COICOP.

3.4.2 Independent Variables

For this survey, there are four independent variables that will be measured. There is the rising prices rate, exchange rate, Money Supply and Palm Oil

Palm oil Monetary value

Harmonizing to the conventional diagram above, it can be elaborated that the Consumer Price Index are determine by the rising prices rate, Exchange Rate, Money Supply and Palm Oil Price.


The statistical tools use in the survey is Multiple Linear Regression Model. This theoretical account of analysis is done to analyze the coincident effects of several independent variables on a dependant variable that is interval scaly. In other used since is can explicate the correlativity between the dependant and independent variable. By utilizing this correlativity we can place which variable will impact most on the dependant variable. This equation is one of the method that easier to utilize and understand.

Multiple Linear Regression Model:

( Equation 1 )

Where ;

Y = Dependent variable which represent Consumer Price Index

= The changeless figure of equation

= Independent variable which represent Inflation Rate

= Independent variable which represent Exchange Rate

= Independent variable which represent Money Supply

= Independent variable which represent Palm Oil Price

= Mistake
