2.5 METHODOLOGY
2.5.1 Definition of population:
The population of this research proposal will be those young adults studying at university that is specified into medium to high level of economical background. The target population of this research will be private university in Subang Jaya, Malaysia.

2.5.2 Sample Plan and Size
The sample size is set at XXX people to obtain a more generalised data. In order to ensure that each targeted individual in the Klang Valley area has the desired characteristics or interest, non-probability sampling, more specifically, judgmental sampling method will be utilised in the sampling selection. Through personally administered questionnaires, judgmental sampling design is usually used when a limited number of individuals possess the trait of interest. It is the only viable sampling technique in obtaining information from a very specific group of people (Castillo, 2009).Furthermore, non-probability sampling uses human intervention (Zhao and Jin, 2006).

In judgmental or purposive sampling, the researcher employs his or her own "expert” judgment about who to include in the sample frame. This means respondents are chosen due to certain characteristics. Prior knowledge and research skill are used in selecting the respondents or elements to be sampled. However, by limiting the sample to only this group, the projections may not be reliable if the sample characteristics may vary from one another. As with all non probability sampling methods, the degree and direction of error in judgmental sampling cannot be measured and statistics that measure the precision of the estimates cannot be calculated.

The study of religion may be as old as humankind itself according to one author. Defining religion is difficult as there are many definitions as there are many authors. The word religion is the most difficult to define because of the lack of a universally accepted definition. Specifically the root meaning of the word religion can be...

Importance of Population and Sampling
History from Political Arithmetic to Statistics
The history timeline show evidence of statistical data as early as Ancient Greece time but records show statistics in late 16th century, when it was introduced by, John Graunt, William Petty, and Pascal and later in 17th century by Gottfried Achenwall. It was an exciting time when success and discoveries raised the...

Statistical data dates back to as early as Ancient Greek time, where it was introduced by John Graunt, William Petty and Pascal in the 16th century. It was then re-introduced by Gottfriend Achenwall in the 17th century. This was a very exciting time for scientists, astronomers and physicists alike as it raised the confidence and knowing that the laws of nature were not of divine intervention. As the years...

...Sampling
Sampling methods are classified as either probability or nonprobability.
In probability samples, each member of the population has a known non-zero probability of being selected. Probability methods include random sampling, systematic sampling, and stratified sampling.
In nonprobability sampling, members are selected from the population in some non random manner. These include convenience sampling, judgment sampling, quota sampling, and snowball...

...Population health is the aggregation of various approach to health care that determines the health outcome of a group of individuals (Nash, JoAnne, Fabius, & Pracilio, 2011). Population health brings together the total quality of health of individuals in the community, considering the disparities in cultures, socioeconomical status, demographics, etc. The outcome of health of individuals in a giving population is highly determined by the...

Hypothesis Test
The sample correlation coefficient r is the estimator of population correlation coefficient r (rho). Recall that relations in samples do not necessarily depict the same in the population. For example, in Figure 6, the population of all dots demonstrates no correlation. If by chance the encircled points were sampled, an inverse association would...
