There are not a few times that, regardless of the field of study or professional orientation, there has been the need to carry out a survey, either in the context of a research paper or to find trends and phenomena in a certain field. This research is basically either quantitative or qualitative. Quantitative research focuses primarily on quantifying data and phenomena. It often involves the use of statistical, mathematical or computational techniques to analyze data collected from surveys, experiments or secondary data sources. But what are these steps that can establish the validity and reliability of a quantitative research?

1. Defining the research problem or question on which the quantitative research will be based

The basis of any research project is a clearly defined problem or question. First, you should clearly articulate what you want to study and why it is important. This includes understanding the context and the specific issues to be addressed. Next comes the definition of the research objectives, which should be specific, measurable, achievable, relevant and time-bound. You will then be asked to develop hypotheses that can be tested through data collection and analysis. A hypothesis is a tentative explanation or prediction that can be confirmed or disproved.

2. Finding literature for the quantitative research you will be doing

A thorough review of the existing literature is the next necessary step to ascertain what research has been done that supports your research question and to identify any gaps that you may be able to fill with your own research. Therefore, the following steps include:

• Search for relevant literature: Use academic databases, journals, books and other sources to gather information about your topic.
• Synthesis of information: Summarize and synthesize findings from previous studies to create a theoretical framework and justify your research.
• Gap Identification: Point out the gaps or inconsistencies in the existing literature that your research aims to remedy.

3. Research design

Choosing an appropriate research design is crucial to the validity and reliability of the research. The steps you should take in this phase include:

• Choosing the research design: Decide between experimental, quasi-experimental or non-experimental designs based on the research question and objectives.
• Choice of Methodology: Determine the specific methods for data collection, such as surveys, experiments, or secondary data analysis.
• Define Operational Variables: Determine how you will measure the variables of interest. Make sure your measures are valid (accurate) and reliable (consistent).

4. Sampling

Sampling involves selecting a subset of the population to participate in the study. For a correct sampling it is important to apply the following:

• Defining the population: Clearly define the population from which the sample will be drawn.
• Choosing a sampling method: Decide on a sampling technique based on the research design and objectives.
• Determining sample size: Calculate the sample size needed to achieve statistical significance. Larger samples generally provide more accurate and reliable results.

5. Collection of data on which to base the quantitative research

Data collection is a critical phase that requires careful planning and execution. This includes:

• Designing data collection instruments: Create or select instruments for data collection, such as questionnaires, tests, or observational checklists. Make sure they are valid and reliable.
• Pilot test: Conduct a pilot test to identify and correct any problems with the instruments or data collection procedures.
• Data Collection: Implement the data collection process, maintaining ethical standards and ensuring its accuracy and integrity.

6. Data analysis

Data analysis involves the organization, interpretation and presentation of collected data. First, don’t neglect to spend time organizing the data, while dealing with any missing values ​​or outliers. Also, it is important to choose the appropriate statistical techniques to analyze the data. research question and research objectives. Finally determine whether the data support or disprove the hypotheses.

7. Reporting and presentation of findings

Communicating the end of your research findings is exactly the step that will win the impression. First, don’t forget to structure your research report to include an introduction, literature review, methodology, results, discussion, and conclusion. Ensure clarity and coherence in the presentation of your findings. At the same time, keep in mind that data visualization can be very useful. Use tables, graphs and pies to present data visually, making it easier to understand and interpret. Finally, discuss the implications of the findings for theory, practice, and future research. In this phase you are given the opportunity to address any limitations of the study and suggest areas for further investigation. In any case, keep in mind that ensuring validity and reliability at every stage of the research is vital to the reliability of the findings.

Pro tip: Leave data analysis and conclusion writing to an expert!
