Lesson 4.1 Quantitative Research Overview Issues to be discussed:
Topic 4.1.1 An Overview of Quantitative Research Topic 4.1.2 Quantitative Research Questions
Objective of Lesson 4.1 Quantitative Research Overview After students study Lesson 4.1, they will be able to: 1. Understand the meaning of quantitative research; 2. Understand the ways in which quantitative research is used in different settings.
Main concepts of Lesson 4.1 Quantitative Research Overview 1. Quantitative research definition and views. 2. Positivism. Topics: 4.1.1 An Overview of Quantitative Research Quantitative research is a formal, objective, systematic empirical investigation of observable phenomena via statistical, mathematical, numerical data or computational techniques and collecting numerical data that are analyzed by using mathematically based methods in particular statistics (Aliaga and Gunderson 2002). This research method is used to describe variables, to examine relationships among variables, and to determine cause-and-effect interactions between variables (Burns and Grove 2005). Phenomena are key elements of all research and they could be questioned like ‘What are the factors that influence advertisers’ achievement in Thailand?’, ‘What is the relationship between public relations and advertising for consumer behavior in Malaysia?’. The idea is linked to what are seen as the philosophies and world views of researchers in quantitative research ‘paradigms’, described as being ‘realist’ or sometimes ‘positivist’.

Topics: 4.1.2 Quantitative research questions. With a pragmatic approach to research methods, the main question that needs to be answered is: ‘What kind of questions or problems is best answered by using quantitative methods?’ However, the first thing is to understand ‘What is a research question (s)/ problem (s)?’ A research problem is a statement about an area of concern, a condition to be improved upon, a difficulty to be eliminated, or a troubling question that exists in scholarly literature, in theory, or in practice that points to the need for meaningful understanding and deliberate investigation. In some social science disciplines the research problem is typically posed in the form of one or more questions. A research problem does not state how to do something, offer a vague or broad proposition, or presents a valued question (University of Southern California, 2015).

Lesson 4.2 Quantitative Methodology Issues to be discussed:
Topic 4.2.1 Population and Sample Topic 4.2.2 Sample Size and Sampling Topic 4.2.3 Research Instrument Topic 4.2.4 Data Collection
Objectives of Lesson 4.2 Quantitative Methodology After students study Lesson 4.2, they will be able to: 1. Critically understand methods used in quantitative research; 2. Understand, identify and analyze the methods that are most suitable for their research project.
Main Concepts of Lesson 4.2 Quantitative Methodology 1. Key terminology and concepts in quantitative research. 2. Sampling methods. Topic 4.2.1 Population and Sample One goal of scientific research is to describe the nature of a population—a group or class of subjects, variables, concepts, or phenomena that usually is a large number of cases representing the interest. Wimmer and Dominick (2006) pointed that in many situations, an entire population cannot be examined due to time and resource constraints. Studying every member of a population is also generally cost-prohibitive and may confound the research because measurements of large numbers of people often affect measurement quality. When focusing on the term ‘population,’ usually we think of people in a town, region, state or country and their respective characteristics such as gender, age, marital status, ethnic membership, religion and so forth. In statistics this term takes on

Module 4 Research Methodology: Quantitative Research l Study Guide
a slightly different meaning that includes all members of a defined group that researchers are studying or collecting information on for data driven decisions. Topic 4.2.2 Sample Size and Sampling The aim of statistical testing is to uncover a significant difference when it actually exists. In its simplest form this involves comparing samples between one regime and another. Sample size is important because larger samples increase the chance of finding a significant difference. However larger samples cost more money. Sample size as an important and controllable influence on the statistical precision or sample error, population values can be estimated. In most applied research settings, limited resources restrict the number of individuals that can be sampled. When choosing a sample size, researcher must consider about what population parameters they want to estimate, cost of sampling, spread of the population, how hard is to collect data, how precise the researcher wants the final estimates to be. Sampling is the process by which inference is made to the whole by examining only a part (Som,1996: 1). There are many types of sampling methods. These will be further explained in the Module. Topic 4.2.3 Research Instrument It is very important to design a good research instrument that will enable us to collect data. In quantitative research, the researcher needs to design a questionnaire. When designing the research instruments, the researcher has to ensure that the focus and aims of the research project are well defined, how the person’s data will be used, the confidentiality respondents’ data, how long will it take to complete the questionnaire, the use of age-appropriate language, the use of appropriate scales, among others. The questionnaire is a reliable instrument and can be online or on paper. Online questionnaires save a lot of time for the researcher to collect data.

Topic 4.2.4 Data Collection Social science researchers look for data to answer their research questions and achieve their research objectives. To a great extent, the data collecting methods affect the quality, quantity, adequacy, and appropriateness of data. There are four main methods of data collection that will be explained in this Module. 1) Census. A census is a study that obtains data from every member of a “population�. It is not practical, because of the cost and/or time required. 2) Sample survey. A sample survey is a study that obtains data from a subset of a population, in order to estimate population attributes. 3) Experiment. An experiment is a controlled study in which the researcher attempts to understand cause-and-effect relationships. The study is "controlled" subjects or treatment. 4) Observational study. Like experiments, observational studies attempt to understand cause-and-effect relationships. However, the researcher is not able to control subjects or treatment.
