2. Infographic Flow: Research Process
3. Meaning of Communication Research
Communication research is the systematic and scientific study of communication processes, messages, media, audiences, effects, institutions and technologies. It helps understand how messages are produced, transmitted, received, interpreted and evaluated in society.
| Research Area | What It Studies |
|---|---|
| Message research | Content, themes, frames, symbols, language and meaning. |
| Audience research | Media habits, preferences, interpretation, uses and effects. |
| Media effects research | Impact of media on knowledge, attitude, behaviour and society. |
| Media institution research | Ownership, policy, newsroom routines, economics and management. |
| Technology research | Digital media, social platforms, ICT, algorithms and online behaviour. |
4. Scientific Method in Research
Scientific research follows systematic observation, logical reasoning, empirical evidence, verification and replicability. It attempts to reduce personal bias and arrive at reliable conclusions.
| Scientific Step | Meaning |
|---|---|
| Observation | Identifying a problem or phenomenon. |
| Question | Formulating what needs to be studied. |
| Hypothesis | Making a testable statement or prediction. |
| Data collection | Collecting evidence through appropriate methods. |
| Analysis | Interpreting data using qualitative or quantitative procedures. |
| Conclusion | Answering the research question based on evidence. |
5. Types of Communication Research
| Type | Meaning | Example |
|---|---|---|
| Historical research | Studies past events, documents and developments. | History of community radio in India. |
| Descriptive research | Describes existing conditions or patterns. | Media use habits among college students. |
| Analytical research | Explains relationships, causes or meanings. | Analysis of news framing in election coverage. |
| Experimental research | Tests cause-effect relationship under controlled conditions. | Effect of violent content on aggression scores. |
| Qualitative research | Explores meanings, experiences, perceptions and context. | Focus group on OTT viewing habits. |
| Quantitative research | Uses numerical data and statistical analysis. | Survey on newspaper readership. |
| Evaluation research | Assesses effectiveness of a programme, campaign or message. | Evaluation of a health communication campaign. |
6. Research Problem, Objectives and Research Questions
A research problem identifies what needs to be studied. Objectives state what the researcher wants to achieve. Research questions guide the inquiry and help decide the method and tools.
| Element | Example |
|---|---|
| Research problem | Low viewership of development-oriented television programmes. |
| Objective | To examine why development programmes fail to attract local viewers. |
| Research question | How does local specificity affect viewership of development programmes? |
| Hypothesis | Development programmes with local specificity receive higher viewership. |
7. Variables in Research
A variable is any quality or characteristic that can vary. Communication research may study variables such as media exposure, age, gender, attitude, knowledge, recall, satisfaction, political affiliation or viewing time.
| Variable Type | Meaning | Example |
|---|---|---|
| Independent variable | Variable that is expected to influence another variable. | Exposure to a campaign. |
| Dependent variable | Variable that is affected or measured as outcome. | Change in awareness or attitude. |
| Control variable | Variable controlled to reduce unwanted influence. | Age group, education level or prior exposure. |
| Intervening variable | Variable that comes between cause and effect and influences the relationship. | Motivation, interest or media literacy. |
| Discrete variable | Variable with separate categories. | Political affiliation, gender category, media ownership type. |
| Continuous variable | Variable measured on a continuous scale. | Age, time spent, income, rating score. |
8. Hypothesis
A hypothesis is a tentative and testable statement about the relationship between variables. It helps guide data collection and analysis.
| Hypothesis Type | Meaning |
|---|---|
| Research hypothesis | Predicts a relationship or difference. |
| Null hypothesis | States that there is no significant relationship or difference. |
| Directional hypothesis | Predicts the direction of relationship. |
| Non-directional hypothesis | Predicts a relationship but not the direction. |
| Operational hypothesis | Defines variables in measurable terms. |
9. Causation
Causation means that one variable produces change in another variable. In research, causation generally requires association, time order and elimination of alternative explanations.
| Condition | Meaning |
|---|---|
| Co-variation | Two variables change together. |
| Time order | Cause must occur before effect. |
| Non-spuriousness | Relationship should not be caused by a third variable. |
