It is also usually a quicker method than, for example, tabulation, the census technique or analysis. 3. Scope of sampling is high The aim of Sampling is to determine generalizations of data of its target market population. Using the whole population to arrive at general conclusions would be practically difficult as in very large populations the population might change before the process is completed. Some populations are also too large so that all their characteristics cannot be measured.
As it is obvious from the title, sample is selected because they are convenient to be selected via selecting whatever persons can be most easily access to accomplish the survey. Convenience sampling is mostly used in preliminary research efforts in order to achieve a gross estimation of results without devoting the required cost and time to gain a random sample. Judgment sampling: this method is a common non-probability sampling method in which the researcher decides which members of the entire population should be selected based on his/her judgment. Since the researcher’s judgment is the criteria for selecting sample, it is necessary that s/he ensures that the selected sample is an appropriate representative of the entire target population and if it is needed some alternative justification for representativeness may be applied. Quota sampling: this method is the non-probability version of the stratified sampling i.e.
Having thought about the aims and objectives to evaluate this research study I had to consider the selection of the preferred method of data collection has a purpose. To evaluate a research study to gain in-depth information, regardless the method style of data collection. The choice of collecting the data depends largely on the question which the researcher wishes to obtain information. However each method has its particular strength and weakness, therefore when researcher chooses a research method, researcher need to use the most appropriate method that support the data collection. A research method consists of four methods to gain data, which is questionnaire,interviews and observation.
Research Methodology This chapter will be based on the methodology used for carrying out this study. It will be answering the research questions in section 1. The research design will be presented as well as the research paradigm. The data collection tools will be studied and data analysis will be described. The reliability and validity of this study will also be described.
Chapter 3: Research Methodology 3.0 Introduction This chapter discusses the techniques or methods that are suitable to be adopted in order to carry out this research. A well-developed methodology is essential to produce a certain degree of accuracy and value of a research. Hence, elements included in chapter 3 are research design, data collection method, sampling design, research instrument, construct measurement, processing of data, and also data analysis. 3.1 Research Design According to Zikmund (2010), research design is a master plan for collecting and analyzing the needed information by specifying the methods and procedures. Creswell (2009) also explains that research design is the research process that involves the overall
Sampling Procedure The goal of the research is to understand and describe students in depth, therefore, the researchers used homogenous sampling under purposive sampling techniques. This sampling procedure was used because all the members of the sample share a common trait according to the criteria of the research. Research instrument The following instruments were used by the researchers in gathering data 1.) Voice recorder that keeps all the information, proof and evidence of what the interviewee was saying. 2.)
For the subject sampling purpose, I decided to use a non-probability sampling approach by only administering surveys to those individuals who were available at the time. The survey was divided and broken down in a questionary form and demographic questions. The survey included a Likert - type 5 point satisfied/ dissatisfied scale; as well as open-ended questions
DQ #2: What are the major advantages and challenges to using a qualitative approach in social science research? Apply these advantages and challenges to your topic of interest. Answer Data collection methods in Social Science research may be grouped into three main categories namely: Quantitative, Qualitative and Mixed research. The research method is basic to the success of any research activity and is essential to maintaining the integrity of research. Krishnamurthi, Cabrera, and Karlovsky, (2004) argue that the selection of the appropriate data collection instruments and their correct use help to reduce or eliminate the likelihood of errors.
