Course number: STAT 702 (395419) Course name: Research Methodology

Academic Year 2011 Course Convenor: Prof Gabriel TATI

Level: Postgraduate (Honours and Masters)

Course Objectives

This is an advanced course on Research Methods purposefully designed for

Postgraduate Students specialising in Applied Statistics, population studies

(MSc and Honours) business sciences. The course draws essentially upon quantitative data analysis and its embedment into research process as is discussed in most relevant textbooks. In order to be able to appreciate the kinds of analyses that are conducted in relation to such data and possibly analyse their own data (especially since students are required to carry out projects for Masters and PhD Thesis), an acquaintance with the wide range and interpretation of descriptive and some knowledge of inferential statistics is highly desirable for post-graduate students. The presentation makes extensive use of worked examples drawn from real-life situations to promote step-by-step understanding of the material presented. This will assist students in consolidating and acquiring problem-solving skills in research methods.

Study questions are placed at the end of each chapter. These study questions are intended to help the students master each topical section, and prepare for the tests and assignments.

Number of credits : 15

Course outcomes:

After completing this course, the students will be able to:

- Understand the significance and the major stages of research process.

- Design and implement their research project.

- Conduct quantitative data analysis with SPSS.

- Communicate their research findings in a scientific manner to target audiences.

Methods of assessment

Two class tests and a series of assignments are scheduled. The possibility of writing a third test will be discussed in accordance with the time allocated to the course. Additionally, the students will be requested to prepare and submit a research protocol at the end of the second term. Selected topics will be specified for Assignments. The guidelines for the preparation of the research proposal will be outlined in due course.

The percentage weighting for class test, assignment and research protocol is as follows: Test (40%), Assignment (10%), Research Protocol (15%) and a

written final exam (35%). The final exam will be written toward the end of June

2011 (a date will be communicated by end May 2011).

Course notes prepared by the lecturer

The Lecturer has prepared relevant course notes that strive to present, in a clear and concise way, the fundamentals of research methods. These notes are presented in two volumes that contain the material examined in part one and part two of the course. Volume one refers to part one and presents the fundamentals and principles of research methodology. The second volume refers to Part Two and presents some basic statistics and introductory applications of SPSS with window. To keep pace with the complexity of each topic presented, students are strongly advised to work out the study questions assigned to them. The two volumes are covered by copy rights.

It is by no means intended to cover exhaustively the various topics. The student should expand the course notes and deepen them by supplementary readings. The list of readings proposed below may serve as sources for valuable information on the topics discussed in class.

The Plan of the Course

Part One

The overall goal of Part One is to offer a comprehensive and systematic treatment of the scientific approach within the context of social science, with special reference to the major programmes taught in the department of

Statistics. Along this line, an emphasis is put on the linkages (relationships) between theory and practice. The underlying intention is to integrate research activities in an orderly framework so that the student can more easily comprehend the nature or social or business science research.

It is widely recognised that research, be it social of natural science, is a cyclical, self-correcting process consisting of seven major interrelated steps: definition of research problem, statement of the hypothesis, research design, measurement, data collection, data analysis, and generalisation. Theory is at the very core of these steps. In other words, theory both affects and is affected by each of them.

The logic underlying the presentation of the course material is to progress

(smoothly) from the conceptual and theoretical building components of the research process to data analysis and some computer applications. Such a progression is intended to offer students a comprehensive and systematic foundation for comprehending the breadth and depth of science research. The course is structured in chapters as follows:

The first and second Topic presents some general epistemological considerations underlying scientific. A synthetic examination is made for these issues related to the foundations of scientific knowledge, scientific knowledge, and the basic assumptions of the scientific approach. Logic in Algebra will be used as an illustration of deduction.

The third Topic is an examination of the conceptual foundations of research, followed by a discussion, Topic 4, of what a theory is (or put differently, what a theory is not) and its relationship, Topic 5, with the usefulness of scientific research outcomes. These topics also look into the issues relating to the concept formation, the roles and types of theories, models, variables, and the various sources for research problems and the construction of hypotheses.

Topic 6 examines the differences in the methodology used in qualitative and qualitative research perspectives.

Topic 7 is an overview of the major steps in the research process with a focus on the conceptualisation (theoretical construction) of the social reality under investigation.

Topic 8, 9 and 10 elaborates on ways in which the research question is broadly initiated and gradually refined to make it investigable. The statement of the research problem is an important step in research process, as it indicates the niche into which the researcher is contributing to the existing body of knowledge. Topic 8 and 9 are specifically concerned with the appropriate way of formulating such a statement from a theoretical perspective.

The modalities pertaining to research design and model construction are examined in details in Topic 11 and 12. The research design is an important stage in the investigation as it provides the logical framework for answering the research question (s), and that way, the logical model for inferring causal relations. Different types of research design will be reviewed in line with their appropriateness to social research. This chapter also examines issues relating to measurement, quantification, validity and reliability. The principles of sampling theory and the practical aspects of sampling designs are presented in the last sections of the chapter. Topic 11 focuses on the formulation of testable hypotheses for the research.

Topic 13, 14, 15 and 16 deal with various methods of data collection available to social and natural scientists. Scientific observation heavily relies on questionnaire construction which follows on theory or conceptual building. The construction of such a questionnaire is examined through the content of questions, types of questions, question format, and the sequence of questions. The chapter will also address some of the frequently encountered pitfalls in the course of questionnaire construction.

Data processing and analysis are discussed in Topic 17. Techniques in codebook construction, coding schemes and preparation of data for computer processing are examined in detail. The chapter also includes guidelines on

data exploring by ways of simple and cross-tabulation, associations and relationships between variables, and summarizing.

Topic 18 is concerned with the interpretation of results. Statistical results may provide the quantitative framework for supporting or refuting the research hypotheses. The limits of statistics with regard to the interpretation of research findings will be underscored in the presentation of the topic.

Topic 19 is devoted to the writing of research report. A report must clearly provide detailed accounts on way in which the research was carried out from the start research question to the interpretation of results. There is no sense in conducting research if the results obtained are not released to the scientific community (for a critical and objective evaluation).

Ethical concerns in research are examined in Topic 20. Any research involving human or animals must comply with ethics. The discussion will revolve around ways of ensuring the rights and the welfare of the research participants, including the right to privacy.

Topic 21 presents the requirements for a convincing proposal for research.

The last part of the volume 1 contains a step-bystep exposé on how to use

Excel to conduct data querying, summarise data via pivot tables and charts, and conduct advanced statistical analysis (with the data-analysis add-in module). It also contains a series of exercises mostly taken from previous test and exam papers written by students from 2005 to 2010.

Part Two

Part 2 of the course is designed for those with no previous strong knowledge of quantitative data analysis, and includes inferential statistics. The emphasis throughout this part two is on understanding the underlying principles of data analysis, and on bringing these out with reference to simple but realistic worked samples using the statistical software package SPSS. The teaching deals exclusively with cross-sectional data. The presentation of the material is organised around four integrated components. The first component consists of substantive chapters presenting the basic principles in statistical measuring. In the second component, key concepts are presented at the end of each chapter, and students should make sure that they understand their meaning, this component also include multiple choice questions at the end of each chapter to be used by students as a small test as a way of assisting in the absorption of some of the main ideas and/or statistical techniques contained in that chapter. The third component consists of substantial assignments involving data analysis tasks on the computer at the end of the chapters. These assignments combine the computing skills which students need to undertake specific pieces of analysis, with an understanding of the statistical procedures presented in the relevant chapters. Assignments also include writing a brief report on each analysis, which will give them practice at

writing up results. The fourth and final component presents computing instructions after the presentation of each chapter. This presentation is primarily concerned with getting across the main points that students need to know about doing data analysis using SPSS on a PC. The basic information about relevant SPSS procedures are presented first, and students only need to follow those instructions to do data analysis. Part two is structured around six practical sessions.
