  2. Part One. The Research Process

  3. Chapter 1: Science and Research • What is Research? • Getting Started • The Development of Mass Media Research • Media Research and the Scientific Method • The Methods of Knowing

  4. Characteristics of the Scientific Method • 1) Scientific research is public • 2) Science is objective • 3) Science is empirical • 4) Science is systematic and cumulative • 5) Science is predictive

  5. Two Sectors of Research: Academic and Private • Research Procedures • 1) Selecting a Research Topic • 2) Professional Journals • 3) Magazine and Periodicals • 4) Research Summaries • 5) The Internet

  6. 6) Everyday situations • 7) Archive Data • 8) Advantages of Secondary Analysis • 9) Disadvantages of Secondary Analysis

  7. Determining Topic Relevance • 1) Is the Topic Too Broad? • 2) Can the Problem Really be Investigated? • 3) Can the Data Be Analyzed? • 4) Is the Problem Significant? • 5) Can the Results of the Study Be Generalized? • 6) What Costs and Time Are Involved in the Analysis?

  8. 7) Is the Planned Approach Appropriate to the Project? • 8) Is There Any Potential Harm to the Subjects?

  9. Stating a hypothesis or Research Question • Data Analysis and Interpretation • Internal Validity • 1) History • 2) Maturation • 3) Testing • 4) Instrumentation • 5) Statistical regression
