Quantitative approach in education generalities
Main advantages of quantitative approach
The use of statistical data for the research explanations and analysis has significant advantages in the research process because the information can be more accurately verified, confirmed and checked.
Besides quantitative approach helps researches to optimize the time and effort invested in analyzing and describing the results gotten.
Using quantitative approach simplifies the possibility of measuring how many and how often “situations” happen as well as, it provides approximations of higher samples size to determine the predictive generalizations of something that needs to be proved, which is really significant to make conclusions.
Quantitative research approach can be employed for doing an investigation that includes a control group and two or more study groups to collect evidence that might become essential when analyzing it statistically.
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.
There are many advantages for using quantitative research which can be summarized in four points mainly.
Collect reliable and accurate data:
Because of the fact that data is “collected, analyzed and presented in numbers”, the outcomes obtained will be really reliable. Using numbers makes researchers to see the issue of study represented in an unbiased and accurate way to objectively analyze it.
Quick data collection:
Data is gotten from a representative group of a population. The methods how data is gathered as well as the manner how it is analyzed by using statistics, saves not only time, but also lessens wasting resources.
Extensive range of data analysis:
With statistics as a useful tool, it also permits a broader collection of data obtained from bigger sample groups, which can be a limitation in other situations.
Eliminate bias:
There is no possibility for own interpretations or preconceptions of results. The outcomes reached are statistical. Thus, they are verifiable.
Quantitative research is principally objective and appropriate for the testing of hypotheses and the results are valid, reliable and generalizable to a larger population.
Some disadvantages of the quantitative approach
it also has some limitations
The focus on numbers found in quantitative research can also be restrictive, leading to some disadvantages
This approach does not succeed in providing enough explanations about the reasons of the effect of certain variables or aspects about the study group within a detailed context.
A second limitation is that positivism paradigm neither describes how reality is “shaped” nor refers to how persons “interpret” their behaviors.
Another limitation of quantitative research approach is that it measures variables in a particular context at a determined moment without measuring those characteristics which might be consistent and contribute a lot to the research, as well.
Quantitative research can be insufficient concentrating only on numbers, because there is the possibility of missing information that can be useful to consider for making final conclusions
Quantitative research tends to be taken as a very useful tool for most of researchers who look for reliability, and confidentially in the data collected predominantly.
