  1. 1. Chapter 6a 6-1 Research Design: An Overview
  2. 2. 6-2 Research Design Research Question/ Hypothesis Research Process Answer/Test Result for Hypothesis Research Design is the detail elaboration (e.g. plan/structure) of the process, particularly the methodology, to investigate the research question/hypothesis
  3. 3. 6-3 Research Design Research Question/ Hypothesis Research Process (Design the Methodology) Answer/Test Result for Hypothesis There can be multiple ways to reach to the answer. But the appropriate way depends on the purpose of the research and the nature of the investigative question/hypothesis Design the research accordingly Exploratory, Causal? Observation, In-Depth Interview Survey, Experimentation? Qualitative or Quantitative Approaches? Primary or Secondary Data? Generalization or Case Study? Note: For qualitative studies there would be no hypothesis.
  4. 4. 6-4 Degree to Structure of Research Question Crystalized Established Hypothesis Clear Objective Precise Procedure (Mostly Quantitative) Defined Data Sources Clear Data Analysis Technique Usually Generalizable Loosely Defined Objective is to enhance understanding Procedure?? (Mostly Qualitative) Research Technique is challenging Tentative Conclusion Leads to Hypothesis Generalization is not the objective EXPLORATORY STUDY FORMAL STUDY
  5. 5. Example of Research Questions that may be addressed with exploratory research approach • How does Covid-19 impacting on the psychological state of mind of the people? • What does it mean to be living in a “New Normal” era? 6-5
  6. 6. • Does the rise in bad management behavior lead to employee turnover in an organization? • What are the factors influence firms in deciding their capital structure? • Identify the factors that are crucial for sustainability of the banking sector of Bangladesh? 6-6 Example of Research Questions that can be addressed with formal research approach
  7. 7. 6-7 Method of Data Collection No Human Interaction Data Collected from Observation, Remote Mode (e.g. CCTV), Machine generated, Archive Example: Traffic count in an intersection Performance analysis based on investigating data generated by systematic process (e.g. productivity, accounting performance) Monitoring
  8. 8. 6-8 Method of Data Collection Human contact is essential Example: Interview or telephone conversation Self administered survey questionnaire sent through email or post Communication
  9. 9. 6-9 The power of the researcher to produce effects in the variables under study Researcher has control over the variable(s) Study involving the manipulation or control of one or more variables to determine the effect on another variable Experiment
  10. 10. 6-10 The power of the researcher to produce effects in the variables under study Experiment Maturity Contractual Obligation Expected risk return tradeoffs Convertibility/Liquidity Financial Asset Features Investment Decision Can be manipulated by the researcher
  11. 11. 6-11 The power of the researcher to produce effects in the variables under study Researcher has no control over the variable(s) Researcher can only report what has happened or happening Ex-Post Facto Study Example of Uncontrollable Variables Political condition Economic Condition Socio-Cultural Condition Legal Framework Competition
  12. 12. 6-12 The purpose of the study Purpose of Study Descriptive Causal Reporting Discover the answers to the questions who, what, when, where, or how much Attempt to reveal a causal relationship between variables. Statistical illustration of data for deeper understanding or comparison e.g. Crime Report: Number of crime per person e.g. Crime Report: type of crime, where it happened, by whom, how often it happens etc. e.g. Research on Crime: Why does a person crime? Find out the factors behind a person inclined to crime
  13. 13. 6-13 The Time Dimension Carried out once and represent a snapshot of one point in time. Repeated over an extended period. This study can track changes over time.
  14. 14. 6-14 The topical scope—Breadth and Depth—of the study Topical Scope Case Study Statistical Study • Depth • Detail • Qualitative • Multiple sources of information • Breadth • Population inferences • Quantitative • Generalizable findings
  15. 15. 6-15 The Research Environment Field conditions (Actual Condition) Lab conditions (Staged Condition) Simulations (Replicated Condition)
