A research can be undertaken for two different
purposes:
1. To solve a currently existing problem
(applied research)
2. To contribute to the general body of
knowledge in a particular area of interest
(basic/fundamental research)
Ways to select a topic


Personal experience
Curiosity based on something in the media
The state of knowledge in a field
Social premiums
Personal values
Major Limitations in
Conducting a Research
Time
 Costs
 Access to resources
 Approval by authorities
 Ethical concerns
 Expertise

Quantitative vs. Qualitative Methodological
Assumption (Cresswell 1994: 5)
Quantitative
Qualitative
Deductive process
Inductive process
Cause and effect
Mutual simultaneous shaping of
factors
Static design – categories isolated
before study
Emerging design – categories
identified during research process
Generalization leading to prediction, Patterns, theories developed for
explanation, and understanding
understanding
Accurate and reliable through
validity and reliability
Accurate and reliable through
verification

Qualitative researchers are concerned primarily with process,
rather than outcomes or products.
Qualitative researchers are interested in meaning.
The qualitative researcher is the primary instrument for data
collection and analysis. Data are mediated through this human
instrument, rather than through inventories, questionnaires, or
machines.
Qualitative research involves fieldwork. The researcher physically
goes to the people setting, site, or institution to observe or record
behavior in its natural setting.
Qualitative research is descriptive in that the researcher in
interested in process, meaning and understanding gained through
words or pictures.
The process of qualitative research is inductive in that the
researcher builds abstractions, concepts, hypotheses, and
theories from details.
Quantitative Methods

Quantitative Descriptive


Descriptive statistics: graphical and numerical
techniques for summarizing data.
Quantitative Analytic

Inferential statistics: procedures for making
generalizations about characteristics of a
population based on information obtained
from a sample taken from that population


Population: any set of individuals (or objects)
having some common observable characteristics.
Sample: the subset of a population which
represents the characteristics of the population.
A sample consists of respondents or subjects
An informant: a person from whom a linguist
obtains information about language, dialect, or
culture.
A corpus is a collection of written or spoken
material.
