When to Use Qualitative and Quantitative
Methods
Qualitative methods generally seek to answer questions that center
around experiences that involve understanding values, beliefs,
perceptions, emotions, culture, growth, paradigm shifts, processes,
taboos, morality, reasoning, and acquiring learning. In short, the more
a question centers around “the human experience,” the more it lends
itself to qualitative means which gather rich experiences, stories, and
examples. An example of qualitative research could be using
grounded theory to develop a new theory of language acquisition by
analyzing data from journals, portfolios, and focus group interviews of
persons learning a new language.
Quantitative methods generally seek to answer questions that center
around how much of something has been acquired such as knowledge,
behaviors, or attitudes. Experiments, correlations, causes, and
descriptions are often the reasons why how much of something is
being measured. An example of experimental research is when a pilot
program is compared with an existing instructional program to
measure the effect of different instructional treatments on how much
students learn. An example of correlational research would be the
effect of parental involvement on GPA. The hypothesis of such a study
may be that higher parental involvement will correlate with higher
GPA. An example of a causal research study is the effect of dogmatic
political preferences on macro-moral reasoning abilities. Perhaps the
assumption is that dogmatic political party views may inhibit one’s
ability to morally think through all aspects of social issues. An
example of descriptive research is when a researcher describes how
many hours of homework 7th grade math teachers give per week.
