Quantitative research methodology is a research method based
on positivism used to doing research on current samples, the sample taking
technique is doing randomly, data collecting used research instrument, and the
data analysis is quantitatively/statistically in order to examine the
hypothesis. Kinds of quantitative research are survey, correlation, experiment,
comparative, and class action research. In this article, the writer would like
to share her ideas about correlation and experimental research in order to
fulfill Data Analysis class led by Zainal Arifin, M. Pd.
Experimental research is a study used to know the influence
of current treatment; or to see the relation between experiment group and
control group. There are 4 kinds of experimental study, they are:
pre-experimental, true-experimental, factorial experimental, and quasi
experimental.
Correlational research is a study which is looking for
relation between variables. To know how big the correlation between those
variables we can calculate it by using bivariate correlational method and
multivariate correlational method (Arikunto: 2002, 40). Bivariate correlational
method is a statistic used to tell how close of those 2 variables, for example
the correlation between subject and student achievement. Multivariate
correlational method is used to 3 variables or more.
Data analysis is the process of systematically searching and
arranging the interview transcripts, field notes, and other materials that you
accumulate to increase your own understanding of them and to enable you to
present what you have discovered to others (Sugiyono: 2015, 334). There are 5
steps in analyzing data: (1) grouping data based on variable and respondent;
(2) tabulating data based on variable from all respondent; (3) present the data
of each variable; (4) calculating to answer problem statement; and (5) calculating
to examine the hypothesis. Furthermore, we also have to test the validity and
reliability by using mean, median & modus; normality; homogeneity; and
significant. We test the normality by using lilliefors table; we test the homogeneity
by using chi-square distribution table; and we test the significant by using
table t distribution two tail.
