What Are the Benefits and Drawbacks of Quantitative Data?

Quantitative data can have both benefits and drawbacks, just like any other thing.

Benefits of Quantitative Data

These are the main benefits of working with quantitative information:

  • Quantitative data can be collected quickly and easily, which allows you to obtain large samples. The larger the sample size, the more precise your conclusions will be. Bias is less common for quantitative data. Random sampling is a method that ensures that a dataset is representative and protects it from bias. This is essential for drawing reliable conclusions.
  • Quantitative data can be analyzed objectively.
  • Quantitative data can be used for statistical analysis because it is compatible with mathematical rules and principles. This reduces the influence of biases by researchers or analysts on the interpretations.

Quantitative Data Has Its Disadvantages

Two main issues to consider when working with quantitative data in a research context are:

Quantitative data can lack context. Context is important in some cases. For example, if you are conducting a survey to determine how customers feel about a new product. Although the quantitative data might indicate that 60% of customers are dissatisfied with the product, it will not reveal why. Sometimes you will need to dig deeper to get valuable insights beyond the numbers.

When using questionnaires and surveys, there is the possibility of bias. This is a more general point that applies to research, but it is important to remember when designing surveys and questionnaires. Research bias can be introduced into questions by the way they are written. It is important to ensure that surveys are designed carefully. This post will explain how to reduce survey bias.

What Data Should I Use in My Research?

Now we are able to distinguish between qualitative and quantitative data. When should you use qualitative or quantitative research? The type of project and the client for which you are working will determine this answer. These are some guidelines to help you get started:

Quantitative research is used when it is necessary to verify or validate a hypothesis or theory. If the data can be clearly shown in numbers. A city census shows the total number of residents, their incomes, and other pertinent information.

Qualitative research is used when you are trying to understand something, such as a concept, an experience, or opinion. You might be testing a series of experiences in your company and need to collect reviews for a certain time period. This is qualitative research.

When you need to use both qualitative and quantitative research: If your research project requires both numerical and non-numerical data.
