The main advantages of quantitative approach

1. Permits to observe, count and analyze the information required using statistical techniques. Therefore, this approach can be considered as being scientific in nature.

2. Helps researches to optimize the time and effort invested in analyzing and describing the results gotten. Depending on the results found, it will be easier to realize which statistical tests can be used to make such analysis more accurately to avoid errors and subjectivity.

3. Using this approach to do a research study is replicability, since it focuses on hypothesis testing based on a well-defined plan and clear objectives that can be repeated at any other time and place obtaining the identical outcomes.

4. Quantitative approach is suitable to answer more precisely some fundamental questions for analyzing data like who, how much, what, where, when, how many, and how. For instance, to measure an aspect of interest of research study by using numbers.

5. Quantitative research is principally objective and appropriate for the testing of hypotheses and the results are valid, reliable and generalizable to a larger population.
