Why use quantitative research

Quantitative research is a type of research that collects and analyzes numerical data. It is used to measure and quantify phenomena, and to test hypotheses about relationships between variables. Quantitative research can be used to answer a wide variety of questions, such as:

  • What is the prevalence of a certain behavior or condition in a population?
  • What is the relationship between two or more variables?
  • What is the effect of an intervention on a population?

Quantitative research is used in a wide variety of fields, including business, education, psychology, and medicine. It is an important tool for researchers who want to understand and explain the world around them.

Advantages of quantitative research

Quantitative research has a number of advantages, including:

  • It is objective and unbiased. Quantitative data is collected and analyzed in a systematic way, which reduces the risk of bias.
  • It is generalizable. The results of quantitative studies can be generalized to larger populations, which means that they can be applied to a wider range of people.
  • It is replicable. Quantitative studies can be replicated by other researchers, which allows the results to be verified.
  • It is powerful. Quantitative research can be used to test complex hypotheses and to identify patterns and relationships in data.

Disadvantages of quantitative research

Quantitative research also has some disadvantages, including:

  • It can be expensive and time-consuming to collect and analyze quantitative data.
  • Quantitative research can be difficult to use to study complex phenomena that involve human emotions, motivations, and behaviors.
  • Quantitative research can be misused to support misleading or harmful claims.


Quantitative research is a powerful tool that can be used to answer a wide variety of questions. However, it is important to be aware of the advantages and disadvantages of quantitative research before using it.
