Inductive vs. Deductive Research Approach

When it comes to research, there are two distinctly different methods that researchers use to study various phenomena – inductive and deductive research approaches. Inductive research builds on specific observations to provide a bottom-up perspective on which researchers base their conclusions. On the other hand, researchers using a deductive approach arrive at a particular conclusion after examining a general theory. While both approaches have their merits, they are significantly different when it comes to processes and objectives. Combining and employing both approaches enables researchers to develop a more comprehensive understanding of the subject. 

In this article, we will explain the inductive and deductive research approaches, examine their key differences, and understand how they are used.  

Inductive Research Approach

The inductive research approach is often used in exploratory research to learn more about a new or unfamiliar topic. When using an inductive approach, researchers start with a particular observation and look for patterns and trends to develop a theory about the phenomenon being studied.

This approach is commonly associated with qualitative research methods that aim to derive general principles and theories from specific observations or data.  

Take, for example, a researcher who is interested in conducting exploratory research on the behavioral changes of children due to prolonged online classes during the pandemic.  

1.  Define the research question: In this instance, the researcher can survey households with children in the 6 to 12 age group. The survey should be designed to specifically elicit responses on the child’s emotional and behavioral changes before and after the pandemic. Data that is generated from the survey will form the basis of the researcher’s observations. 
2. Collect data and identify patterns: Once the data has been collected, it needs to be analyzed. The researcher will need to look for patterns and trends that can be used to develop a hypothesis about the phenomenon being studied. For example, he may find that children have become irritable and withdrawn while attending online classes during the pandemic. 
3. Conclude: The final step typically includes a summary of the research question, a description of data collection methods, an analysis of the data, and a discussion of the findings. Normally, the conclusions are not definitive but serve as a starting point for further investigation. 

Deductive research approach 

Unlike inductive reasoning, deductive research is used to test an existing theory. It is also often called confirmatory research and is driven by the scientific method. This approach is usually associated with quantitative research. Let’s take a look at the example below.  

1. Define the research question: The first step in deductive research is to define the research question. It should be something that can be answered with empirical data. As an example, ‘Is the rising cost of petrol leading people to switch to electric cars?’ 
2. Develop a hypothesis: The hypothesis should be based on the researcher’s knowledge of the topic being studied and should predict the outcome of the study. So, in the example provided, the hypothesis is ‘Those with electric vehicles save more than those using petrol or diesel cars.’ 
3. Collect data to test the hypothesis: Data can be collected through different methods, including surveys, interviews, and observations from a specific study set. In this case, data can be gathered from households in a specific locality who use electric and non-electric cars. Once the data has been collated, it must be analyzed to determine whether the results support the hypothesis. 
4. Examining and reporting the outcome: The final step will be to write the research report based on which the hypothesis can be accepted or rejected. If the hypothesis is confirmed, researchers can refine and enhance the existing theories. If the hypothesis is not supported, they may need to revise or develop new theories to explain the research question. 

Combining inductive and deductive research approaches 

While inductive and deductive approaches differ in their process and objectives, they are not mutually exclusive. Researchers handling large projects usually choose to utilize both. There can also be cases where a researcher begins with one approach but later combines it with the other to enrich the research study. This helps them develop more effective solutions to problems and make better decisions.  

The choice of taking either the inductive or deductive research approach depends a great deal on the availability of relevant literature and theories. In instances where data sources are readily available, researchers may prefer a deductive approach, while limited sources mean that an inductive research approach would work better.

However, both approaches present a chance for research to be tinged with bias. Therefore, researchers must be vigilant in ensuring that they do not consciously lean towards their ideas as they process insights and data collected during research.
