How important is choosing an appropriate research design and sample for the study?

Choosing the right study design is the most important decision to make in determining the methodology of any research study. This is important for the way in which the study will be conducted, especially the sampling and data analysis. Study designs are different for qualitative and quantitative research.

What is research methodology and research methods?

Research methods are the techniques and tools by which you research a subject or a topic. Research methodology involves the learning of various techniques to conduct research and acquiring knowledge to perform tests, experiments, surveys, and critical analysis.

What are the rules in choosing a research topic?

Selecting a Topic

  • brainstorm for ideas.
  • choose a topic that will enable you to read and understand the literature.
  • ensure that the topic is manageable and that material is available.
  • make a list of key words.
  • be flexible.
  • define your topic as a focused research question.
  • research and read more about your topic.

What considerations must be given to the selection of a quantitative or qualitative methodology for a research study?

Quantitative researchers must collect evidence of validity and reliability. Some qualitative researchers also aim to establish validity and reliability. They seek to be as objective as possible through techniques, including cross-checking and cross-validating sources during observations.

What is the data preparation process?

Data preparation is the process of cleaning and transforming raw data prior to processing and analysis. For example, the data preparation process usually includes standardizing data formats, enriching source data, and/or removing outliers.

What are the major five steps in the collection of primary data?

This process consists of the following five steps.

  1. Determine What Information You Want to Collect. The first thing you need to do is choose what details you want to collect.
  2. Set a Timeframe for Data Collection.
  3. Determine Your Data Collection Method.
  4. Collect the Data.
  5. Analyze the Data and Implement Your Findings.

How important is a research methodology in helping us address a problem?

The study of research methods gives training to apply them to a problem. The study of research methodology provides us the necessary training in choosing methods, materials, scientific tools and training in techniques relevant for the problem chosen.

What criteria would you use to select the best research design?

Criteria for Selecting a Research Approach

  • The Research Problem and Questions. A research problem, more thoroughly discussed in Chapter 5, is an issue or concern that needs to be addressed (e.g., the issue of racial discrimination).
  • Personal Experiences. Researchers’ own personal training and experiences also influence their choice of approach.
  • Audience.
