When using this type of research, you have to ensure that you are financially prepared. Since you need a huge number of correspondents, you have to spend more cash for printing the questionnaire, transportation fees and a lot more. This is more costly compared to qualitative research. Using quantitative research also provides multiple benefits and few drawbacks. If you want to get the full benefits of this research, you need to know how it works.

Before conducting a data, it is best to know your possible correspondents. You are also required to know how to interpret data and other related factors. This quantitative research is best if you are planning to conduct a study about hypothesis and huge statistical examination. In case you are planning to have a small group of correspondent, it is best to use other methods.

The best way to get a reliable result is by getting more correspondents. The more correspondents you have, the better statistics you will get. Both methods are quite useful depending on the type of study. Some dissertations and research studies take a mixed method approach, which incorporates qualitative and quantitative methods in different phases to obtain a broader perspective.

You may be very familiar with quantitative research from your science classes where you learned and practiced using the scientific method.

A problem or question is examined by deductively forming a hypothesis derived from theory. Controlled, objective testing and experimentation ultimately supports or rejects your hypotheses. Each step is standardized to reduce bias when collecting and analyzing data. A big advantage of this approach is that the results are valid, reliable and generalizable to a larger population. Quantitative research is advantageous for studies that involve numbers, such as measuring achievement gaps between different groups of students or assessing the effectiveness of a new blood pressure medication.

While quantitative research methods work well in the laboratory under tightly controlled conditions, measuring phenomena like human behavior in natural settings is trickier. Survey instruments are vulnerable to errors such as mistakes in measurement and flawed sampling techniques. Another disadvantage is that quantitative research involves numbers, but some topics are too difficult to quantify in numbers.

For example, constructing an effective survey with closed-ended questions about how people fall in love would be difficult. Qualitative research is often used to conduct social and behavioral studies because human interactions are more complex than molecular reactions in a beaker. Subjectivity, nonrandom sampling and small sample size distinguishes qualitative research from quantitative research.

Another advantage to qualitative research is the researcher gains more detailed and rich data in the form of comprehensive written descriptions or visual evidence, such as photographs. This type of research looks at context and social meaning and how it affects individuals, which is advantageous particularly in the social sciences. The researcher of a study using qualitative research is heavily involved in the process, which gives the researcher a subjective view of the study and its participants.

The researcher interprets the research according to his or her own biased view, which skews the data gathered. Another disadvantage is that this research method is very time consuming and can last for months or even years. Quantitative research allows the researcher to measure and analyse data.

The relationship between an independent and dependent variable is studied in detail. This is advantageous because the researcher is more objective about the findings of the research. Quantitative research can be used to test hypotheses in experiments because of its ability to measure data using statistics.

A truly important point in the comparison between quantitative research and qualitative research is that the subjective participation of the researcher -- that is one of the most resilient objections regarding qualitative research -- takes place in quantitative approaches.

But, both the methods and approaches (qualitative and quantitative) have pros and cons. This study, therefore, aims to discuss the advantages and disadvantages of using qualitative and quantitative research approaches and methods in language testing and assessment research. There is a focus on ethical considerations too. The advantages and disadvantages of qualitative research are quite unique. On one hand, you have the perspective of the data that is being collected. On the other hand, you have the techniques of the data collector and their own unique observations that can alter the information in subtle ways.
