Chapter 7 The research design - Coggle Diagram

- - - - In simpler terms, a research design is a plan or strategy that outlines how a research study will be conducted, from formulating hypotheses to analyzing data. It includes decisions about the sample to be studied, data collection methods, and data analysis techniques. The purpose of a research design is to ensure that the study is valid, objective, accurate, and efficient. It is important for researchers to carefully consider and justify their decisions in the research design, and support them with evidence from existing literature. This ensures that the results obtained from the study are reliable and can be used to answer the research questions or problems.
    - - In order to isolate the effects of
        the counselling service on the marital problems, you need to design your study in a way that controls for these external factors. This could involve randomly assigning participants to either receive the counselling service or not, and then comparing the outcomes between the two groups. This helps to ensure that any changes in the marital problems can be attributed to the counselling service and not other external factors.
      - Another example could be a study on the effectiveness of a new teaching method in improving student achievement. In this case, you may want to control for factors such as prior knowledge of the subject, motivation, and socioeconomic status. This could involve selecting a sample of students with similar backgrounds and randomly assigning them to either receive the new teaching method or not. By controlling for these external factors, you can be more confident that any changes in student achievement can be attributed to the teaching method.
      - In summary, a research design plays a crucial role in ensuring the validity and accuracy of a study. It helps to identify and control for external factors that may influence the outcome of the study, making the results more reliable and trustworthy.
    - - Overall, a research design serves as a roadmap for conducting a study and ensures that the procedures used are adequate and valid in obtaining answers to research questions. It outlines the various tasks and procedures that will be used, identifies the study population and how it will be selected, and explains the methods of data collection and ethical considerations. A clear and detailed research design is crucial for ensuring the quality and validity of a study.
    - - The research design serves two important functions. First, it outlines the procedures for conducting a study, including the type of study design, selection of respondents, data collection and analysis methods. Second, it ensures that the independent variable has the maximum opportunity to affect the dependent variable while minimizing the effects of extraneous and chance variables. The control of variance is achieved through the establishment of association or causality and the introduction of a control group to quantify the impact of extraneous and chance variables. The study design is a part of the overall research design, which includes other details related to conducting the study.
