Quantitative Research

12:58 AM



Quantitative Research




One of the design of the research is quantitative research. Here, I want to eplain about quantitative research based on its purpose, approach, process, assumption, role of researcher and methods.


1.      Purpose of the Quantitative Research
            According to Merriam (1998) in Ary’s book (2010:423), he stated that purposes of Quantitative Research are to generalize findings, to predict behavior, to provide causal explanations . It can conclude that the result of the quantitative research can generalize to the population. To predict behavior means that the researcher can predict the problem because the research have already existed by the researcher before, usually the variable relates with cause and effect


2.      Approach of Quantitative Research
            According to Merriam (1998) in Ary’s book (2010:423) he stated  that the approaches of quantitative research are using theory to ground the study, uses manipulation and control variable, deductive then inductive, looks for the norm, reduces data to number and reports written in precise, abstract language. It can conclude that  in quantiative research  the researcher use the theory of the researcher before or the proffessional so the variable is clear, and the researcher can make the hypothesis before they
conduct a research. The data analyse usually uses statistical analysis like T-test.


3.      Process of Quntitative Research
According to Sugiyono (2008: 30) “ Proses peneltian kuantitatif dikembangkan dari proses rumusan masalah, landasan teori, perumusan hipotesis, pengumpulan data, (populasi dan sampel, pengembangan instrumen dan pengujian instrumen), analisa data”. 


4.      Assumption of Quantitative research
            According to Merriam (1998) in Ary’s book (2010:423) he stated the assumptions of quantitative research are there is an objective reality, the world is stable, variables can be identified and measured and quantitative research is rooted in logical empiricism. It can conclude that basically Quantitative research must be objective and logic. 


5.      Role Of Researcher in Quantitative Resarch
According to Merriam (1998) in Ary’s book (2010:423) he stated that role of researcher of quantitative research are:
a.       Detached and impartial
Means that in quantitative research, reasearcher must be neutral during the reaserch. Researcher only report the result of test without any subjective opinion.
b.      Objective portrayal
The data that reported by researcher must be objective using numerical data based on the result of the test means that Researcher can’t manipulate the data.
c.       Inquiry should be as as value free as possible
It means that researcher must follow the procedures and remove subjective elements.  They don’t need be aware about subject characteristics such as their social class, IQ, previous academic, achievement, etc.

6.    The Methods Of Quantitative Research
According to Merriam (1998) in Ary’s book (2010:423) he stated the methods of quantitative research are :
a.    Focused on quantity (how much, how many)
     The researcher must collecting numerical data to explain a particular phenomenon.
b.    Experimental, empirical, statistical focus.
     Experimental to comparing one design or process to another. It’s to deciding on the importance of a particular feature in a user interface and evaluating a technology or a social intervention in a controlled environment. It’s also to finding out what really causes an effect and finding out if an effect really exists.
     Hypotheses of experimental include: a). A causes B. b) A is bigger, faster, better than B. c) A changes more than B when we do X. Two requirements of experimental :Independent variable that can be manipulated and Dependent variable that can be measured.
     Empirical is defined as a descriptive about what “is” the case in the “real world” rather than what “ought” to be the case. Empirical statements are expressed in numerical terms. For example, “Are the numbers of students in our university rising or falling?”. We’ll need to do a quantitative study to find out.
     Statistical focus while the way in analyse data matters, if we haven’t designed our  research well, and collected the data in a valid andreliable way, we will not get valid results however sophisticated analyses.The use of statistics to analyse the data is, however, the element that puts a lot of people off doing quantitative research, as the mathematics underlying the methods seems complicatedand frightening.
c.    Predetermined, structured methods, precise.
     The method of quantitative research is predetermined by the researcher before. So, it means that the method is structured.
     In precise we need techniques that enable us to make valid inferences from samples to whole population. The result must be accurate, so we need a test to get a true result.
d.   Random sampling is ideal.
     According to Sugiyono (2008:82) he states, “dikatakan random sampling karena pengambilan anggota sampel dari populasi dilakukan secara acak tanpa memperhatikan strata yang ada dalam populasi itu”. It can conclude that random sampling just can apply if the condition of the population is homogen.
e.    Uses inanimate instrument (scales, tests, questionnaires, observation checklist, etc).
     According to Sugiyono (2008:92) he states, “skala pengukuran merupakan kesepakatan yang digunakan sebagai acuan untuk menentukan panjang pendeknya interval yang ada dalam alat ukur, sehingga alat ukur tersebut bila digunakan dalam pengukuran akan menghasilkan data quantitative.”
     Test is used to measure how far the research successful or not. Then, questionnaires is written questions that used to get information from respondent and the answers has been already to choose.
     Observation checklists is list of questions to collect the data. The participants just give a sign of aspect in column.
