3.1 Introduction
In this chapter I will discuss about the methodology of this project. Several methods are used to determine the research objective. Methodology is a systematic way to solve a problem. It is a science of studying how research is to be carried out. Essentially, the procedures by which researchers go about their work of describing, explaining and predicting phenomena are called research methodology. It is also defined as the study of methods by which knowledge is gained. Its aim is to give the work plan of research. By understanding and using the appropriate methodology in developing the research, it will be easier to achieve or accomplish the system development objective.
3.2 Sampling Population and Data Gathering Process
Sampling population is referring to the group or individuals that represent the real population for the purpose of analyzing and gathering data. It is possible to gather data with the people who are related to the specified fields. For this project, the study includes thirty participants where age between nineteen to twenty eight years old to gather ...
I will need to take a sample from the population, which is a list of
For everything that occurs, there will somehow be something that caused the action to happen. It is more of a cause and effect ideal or simple a reaction to an action. In terms of research academics, independent and dependent variables are concepts or attributes to certain things that occur such as drug use, crime, or domestic abuse. For example, stress or other personal problems may lead to someone to use drugs. Also, poverty may lead someone to commit crime. In addition, a power controlled individual may cause a partnership to suffer physical or verbal abuse.
This chapter will provide knowledge and understanding of the research process that was carried out, before revealing the results. Methodology is the foundation on which a researcher bases their work. This process is fundamental to the research project as a whole as illustrated in Ryan et al (2002): ‘the process of research is as important as the output’ (p.2).
Research is finding out information in relation to a hypothesis a researcher has constructed in order to prove or disprove it. Research designs refer to the way in which this information is collected in order for it to be analysed, it provides a standard layout for data collection. A research design is chosen by the researcher in order to fit the criteria of the required data to satisfy their hypothesis. The two forms of research designs discussed in this essay will be Experimental and Correlational research.
This essay is going to critically discuss the advantages and disadvantages of using surveys and questionnaires as a method of Socio-Legal research. When conducting socio-legal research, a number of methods can be used to collect useful information.
For example, in a study of criminal justice among juvenile offenders, a single child is considered a sampling unit. A sampling unit could also be a group of elements in a population that the researcher uses for choosing members of the sample population. For instance, a household of consumers could be considered as a sampling unit during marketing researchers. Sampling units usually share common characteristics thus provide the researcher with invaluable information that is useful for drawing conclusions during the research
In this paper, I will define quantitative and qualitative research methods and provide examples in the context of social issues which will hopefully provide insight into how this methods are properly applied.
Following the next chapter describes the research methodology. This methodology divided into five stage process followed by main objective; theoretical study, model development, design prototype, develop prototype and model evaluate. Each stage will be briefly described in the next chapter.
This paper discusses different types of sampling techniques used in quantitative research. It begins by looking at probability sampling (also known as random sampling) before discussing non-probability sampling (non-random sampling). The discussion ends by looking considerations that should be made before selecting a sampling technique before concluding. Because quantitative researchers prefer probability sampling and only use non-probability on rare occasions the e...
... scales present individuals with positively or negatively stated propositions and solicit respondents' opinions about the statements through a set of response keys.
In chapters 1 and 2, I discussed the problem of successfully implementing computer technology for literacy instruction in the classroom, the need to study the importance of making technology an integral part of literacy education, and the theoretical frameworks of new literacies and constructivism. In this chapter, I will detail the research methodology and forms of data collection I have chosen to use to determine how this study can provide new research for the integration of computers in the classroom as it applies to current and future literacy instructional models.
A research design is defined as a plan or blueprint of how one intends to conduct research (Mouton, 2005:55). A research design focuses on the end product of the research process, that is, the type of study being planned and the type of results aimed at. Its point of departure is the research problem, and hence it focuses on the type of evidence required to address the problem adequately.
Research which is also known as the search for knowledge is an art of scientific search for specific information. According to Clifford Woody, the research includes defining and redefining problems, formulating hypothesis and suggested solutions, collecting, organising and evaluating data, making deductions and reaching conclusion and further testing whether the conclusion will fit into formulating hypothesis. Research Methodology is a scientific and systematic way of finding solution to a problem. In this research, researcher has studied various steps for research like problem along with the logic behind them. For this study, researcher must know various research techniques like mean, mode,
Striating from the research idea to the culmination of the findings, the research process entails many segments, all of which are imperative. By choosing the research methodology, the researchers can formulate the path to be used in conducting the study and reporting the findings. The methodology helps in the search of literature, development of research questions and the creation of the most suitable study design. It also assists in the interpretation of the results and the publication of the findings in journals.
The word qualitative assumes an emphasis on the qualities of object and on processes and meanings that are not experimentally examined or measured from the point of quantity, amount, depth, or periodicity. Qualitative researchers accent the socially constructed nature of actuality, the close relationship between the researcher and what is studied, and the situational imperatives that shape demands. Researchers look for answers to questions that accent how social experience is created and given meaning. In contrast, quantitative studies stress the dimension and analysis of causal relationships between variables, not processes. Qualitative forms of demand are thought-out by many social and behavioral scientists to be as much a perspective on how to approach investigating a research problem as it is a method. Denzin, Norman.
