What is Explanatory Research?
Explanatory research is defined as a type of research designed to explain the reasons behind a phenomenon or the relationships between variables. Unlike exploratory research, which seeks to understand and identify new aspects of a topic, explanatory research aims to clarify how and why certain variables influence each other. It is often used to test theories and establish causal relationships, providing a deeper understanding of the underlying mechanisms at play.
In explanatory research, researchers use structured methodologies to investigate hypotheses about causal relationships. This type of research often involves quantitative methods, such as experiments or surveys, to test these hypotheses and determine the strength and nature of the relationships between variables. By employing statistical analysis and controlled experimentation, explanatory research can identify causal links and provide evidence-based explanations for observed phenomena.
For instance, consider a study investigating the impact of employee motivation on productivity in a company. Explanatory research would aim to determine not only whether there is a relationship between motivation and productivity but also how motivation influences productivity. Researchers might conduct controlled experiments or use statistical models to measure the effect of different motivational strategies on employee output, thereby providing a clearer understanding of the causal relationship between these variables.
Key Characteristics of Explanatory Research
Explanatory research is characterized by several key features that differentiate it from other types of research. These characteristics include:
1. Causal Analysis
Explanatory research focuses on understanding and establishing causal relationships between variables. It aims to determine how changes in one variable (independent variable) affect another variable (dependent variable). This involves identifying the mechanisms or processes through which these causal effects occur.
2. Hypothesis Testing
This type of research typically involves formulating and testing hypotheses to validate or refute theoretical propositions. Researchers design studies to test specific predictions about how variables interact, often using statistical methods to assess the strength and significance of these relationships.
3. Quantitative Methods
Explanatory research often employs quantitative methods, such as experiments, surveys, and statistical analysis. These methods provide a structured approach to data collection and analysis, enabling researchers to measure the impact of independent variables on dependent variables with precision and reliability.
4. Controlled and Systematic Approach
To ensure accurate results, explanatory research involves a controlled and systematic approach to data collection and analysis. Researchers use experimental designs, control groups, and randomization to minimize biases and isolate the effects of the independent variable on the dependent variable.
5. Theory Testing and Validation
Explanatory research is instrumental in testing and validating theories or models. By providing empirical evidence on causal relationships, it helps in refining or challenging existing theories and contributes to the development of new theoretical frameworks.
Explanatory Research Method: Key Stages with Examples
Explanatory research involves several key stages to systematically investigate causal relationships and provide a deeper understanding of how and why variables are related. Here’s an outline of these stages with examples for clarity:
1. Defining the Research Problem and Hypotheses
- Identify the Issue: Clearly define the problem or phenomenon that needs explanation. This involves understanding what specific causal relationships you aim to explore.
- Formulate Hypotheses: Develop hypotheses that propose a causal link between variables.
Example: If researching how employee motivation affects productivity, the hypothesis might be: “Increased employee motivation leads to higher productivity.”
2. Designing the Research Methodology
- Select Research Design: Common designs include experiments, longitudinal studies, and controlled surveys.
- Define Variables: Identify and define the independent (predictor) and dependent (outcome) variables in the study. Also, determine any control variables needed to isolate the effects of the independent variable.
Example: In an experiment, you might design a study where one group of employees receives a new motivational incentive (independent variable), and their productivity (dependent variable) is measured over time versus a control group who did not receive the incentive.
3. Data Collection
- Gather Data: Collect data using methods consistent with your research design.
- Ensure Validity and Reliability: Use reliable and valid measures to ensure the data accurately represents the variables being studied.
Example: Administer a productivity survey to employees before and after the introduction of the motivational incentive, ensuring that the survey questions are consistently applied and valid for measuring productivity.
4. Data Analysis
- Analyze Data: Use statistical methods to test the hypotheses and examine the relationships between variables. Techniques such as regression analysis, ANOVA, or structural equation modeling may be employed to determine causal links.
- Interpret Results: Evaluate the results in the context of the hypotheses. Assess whether the data supports the proposed causal relationships and consider the implications for the theory or model being tested.
Example: Perform a regression analysis to determine if there is a statistically significant relationship between the motivational incentive and changes in productivity. Analyze the data to see if the increased motivation leads to measurable improvements in productivity.
5. Reporting and Drawing Conclusions
- Compile Findings: Prepare a detailed report of the research findings, including the methodology, data analysis, and results. Discuss how the findings support or refute the hypotheses.
- Draw Conclusions: Based on the results, draw conclusions about the causal relationships between the variables. Consider the implications for theory, practice, and future research.
Example: Conclude that the motivational incentive has a positive effect on productivity based on the data analysis. Discuss how these findings support the hypothesis and suggest potential applications for improving employee performance in the workplace.
6. Review and Refinement
- Evaluate the Study: Review the research process to identify any limitations or areas for improvement. Consider how the study could be refined or expanded in future research.
- Suggest Future Research: Based on the findings, propose additional research to explore related questions or further validate the results.
Example: Reflect on whether the study’s design could be improved, such as including more diverse samples or different motivational strategies, and suggest future research to explore these aspects.
