How to Write the Method Section of your Research Paper in 03 Simple Steps?

Method Section in Research Paper



The method section is the core part of any research paper. The method section highlights the procedure used to obtain the results by following an innovative or modified approach to the existing methods. The method section usually begins with a block diagram.

The method section of a research paper represents the technical steps involved in conducting the research. Details about the methods focus on characterizing and defining them, but also explaining your chosen techniques, and providing a complete account of the procedures used for selecting, collecting and analyzing the data.

The method section of a research paper should fully explain the reasons for choosing a specific methodology or technique. Also, it’s essential that you describe the specific research methods of data collection you are going to use, whether they are primary or secondary data collection. The methods you choose should have a clear connection with the overall research approach and you need to explain the reasons for choosing the research techniques in your study, and how they help you understand your study’s purpose.

In the method section, you need to explain the rationale of your article to other researchers. You should focus on answering the following questions:

  • Which research methods did you use?
  • Why did you choose these methods and techniques?
  • How did you collect the data or how did you generate the data?
  • How did you use these methods for analyzing the research question or problem?

Based on the questions the following three sections can be identified for writing the research method in question.

1. Selection of research method and justification
2. Data Collection or generation
3. Experimental setup

Selection of Research Method and Justification

When writing the method section of a research paper, it is important to explain why you chose a particular research method and how it will help you achieve the aims of your study. The selection of a research method should be based on the research question, the data that you need to collect, and the type of analysis that you plan to conduct.

For example, if you are conducting a study on the effectiveness of a new algorithm for solving a particular problem, you might choose to use a randomized controlled trial as your research method. This would involve randomly assigning participants to either an experimental group (which uses the new algorithm) or a control group (which uses an existing algorithm). You would then compare the outcomes between the two groups to determine whether the new algorithm is more effective.

In this case, the justification for using a randomized controlled trial is that it allows you to control for confounding variables that might affect the outcomes of your study. By randomly assigning participants to the groups, you can ensure that any differences in outcomes are due to the algorithm and not other factors.

Another example from computer science is if you are conducting a study on user behaviour in a social networking platform, you might choose to use a survey as your research method. This would involve collecting data from users through an online questionnaire, and asking questions about their behaviour and preferences on the platform.

The justification for using a survey, in this case, is that it allows you to collect data from a large number of users in a relatively short amount of time. You can then use statistical analysis to identify patterns and trends in the data, which can help you make informed decisions about the design of the platform.

In addition to explaining why you chose a particular research method, it is important to discuss any potential problems that you anticipated and the steps you took to prevent or minimize them. For example, if you are conducting a survey, you might discuss how you ensured the validity and reliability of the survey questions, how you recruited participants to ensure a representative sample, and how you minimized the risk of non-response bias.

Overall, the selection of a research method and justification is a critical component of the method section in a research paper. It is important to carefully consider the research question, the data you need to collect, and the type of analysis you plan to conduct in order to choose the most appropriate method for your study.

Data Collection or Generation

Readers, academicians and other researchers need to know how the data used in your academic article was collected. The research methods used for collecting or generating data will influence the discoveries and, by extension, how you will interpret them and explain their contribution to general knowledge. The most basic methods for data collection are as follows:

Primary Data

Primary data represent data originated for the specific purpose of the study, with its research questions. The methods vary on how Authors and Researchers conduct an experiment, survey or study, but, in general, it uses a particular scientific method to gather data.  Here readers need to understand how the information was gathered or generated in a way that is consistent with research practices in a field of study.

For primary data, that involve surveys, experiments or observations, authors should provide information about

  • Devices/equipment used for data collection
  • Under what conditions were data collected ( Summer, winter, morning, evening, temperature etc)
  • Longitude and Lattitude where data is collected (Exact location)
  • If the camera is used then: Camera configuration, resolution, distance and angle between the camera and object under observation
  • If any sensors are used then their configuration and operating environment need to be specified
  • If  data is collected from living beings then species name, sex, age etc needs to be provided
  • Inclusion or exclusion criteria  used for data  collection

Example: In the current work, the images of diseased samples of pomegranate leaves are captured using a Nikon Coolpix L20 digital camera having 10 megapixels of resolution and 3.6x optical zoom, maintaining an equal distance of 16 cm to the object. All the images are then saved in the same format i.e., JPEG. For the purpose of image acquisition, authors have visited and
captured images from several pomegranate farms in the places of Hagaribommanahalli(15.0456° N, 76.2074° E), Bellary district and Kaladhagi (16.2050° N, 75.5015° E), Bagalkot district of Karnataka, India.

Secondary Data

Secondary data are data that have been previously collected or gathered for other purposes than the aim of the academic article’s study. This type of data is already available, in different forms, from a variety of sources.  Here Authors should provide information about the following:

  • From which website data is collected
  • On which date the data is collected (can be specified in references)
  • what specific data within the data set is used for the experiment

Example: Our predictor algorithm is tested for real-life benchmark datasets available at  CAVIAR Project (EC Funded CAVIAR  project/IST 2001 37540) to check for relative error. The data set consists of different human motion patterns observed at INRIA Lab at Grenoble, France and Shop Centre. These motion patterns consist of frames captured at 25 frames/second.

When it comes to data collection or generation, researchers often face the challenge of having to label their data. There are two main approaches to data labeling: using existing data labeling software and outsourcing the labeling process.

With existing data labeling software, researchers can utilize pre-existing tools and platforms to label their data efficiently and accurately. This can save time and resources, as well as ensure consistency in the labeling process.

On the other hand, outsourcing the data labeling process to external providers can also be a viable option, especially when dealing with large datasets or complex labeling tasks. Outsourcing can also help researchers save time and resources, while benefiting from the expertise and experience of professional data labeling services. By carefully considering their options and choosing the right approach for their needs, researchers can ensure that their data is labeled accurately and efficiently, enabling them to conduct their research with confidence.

Experimental Setup

Here you need to describe and explain your chosen methods and relate them to your research questions and/or hypotheses. The description of the methods used should include enough details so that the study can be replicated by other Researchers, or at least repeated in a similar situation or framework. This information is particularly important when a new method has been developed or an innovative use of an existing method is utilized.  Detailed discussion on the following points is essential in the method section.

  •  Instruments used and their configuration.
  •  Computing machine (like server/desktop/laptop) configuration, speed, memory size etc.
  •  The software setup and the algorithms applied in computation.
  •   If deployed on the Cloud platform then cloud setup.

Example: Let me take an example from one of my research papers ” Diagnosis and Classification of Grape Leaf Diseases using Neural Networks”
The goal of research work is to diagnose the disease using image processing and artificial intelligence techniques on images of the grape plant leaf. In the proposed system, a grape leaf image with complex background is taken as input. Thresholding is deployed to mask green pixels and the image is processed to remove noise using anisotropic diffusion. Then grape leaf disease segmentation is done using K-means clustering. The diseased portion from segmented images is identified. Feedforward Back Propagation Neural Network was trained for classification.

Here the Method Section is divided into several sub-sections such as
A. Image Acquisition:
B. Background Removal:
C. Preprocessing:
D. Segmentation: Using K-means Clustering Algorithm
E. Extract Lesion:
F. Feature Extraction:
G. Classification: Using Backpropagation Neural Network

What Next? : After the Method section

The method section of a research paper provides a detailed account of the research design and procedures used to collect and analyze data. Once the data is collected and analyzed, the results section is where researchers present their findings to the reader. In the results section, researchers can provide tables, graphs, and statistical analyses to help readers understand the key findings of the study. To learn more about how to effectively present your research findings in the results section, check out our blog post on How to write Results Section of your Research Paper. By following the guidelines given in the blog post, you can ensure that your research results are presented in a clear, concise, and effective manner, helping to maximize the impact of your study.
