STEPS IN A CASE STUDY
METHOD

Identify the Problem of the
Study
All studies require that a research problem
be identified and stated, and must be
simple, concise, and in clear terms. Such
problem will be the focus of a case study.

State the Objectives of the Study
The General and specific objectives of
the study must be categorically
expressed. Such objectives will be the
bases in conducting research activities.

Determine the Sources of Data
The research must identify his sources
of data or information, how he is going
to select his sources, what variables
are to be included and excluded, and
how these variables are to be selected
or determined.

Determine the Procedures of
Investigation
The researcher should identify the procedures
of data gathering, the tools used in data
gathering so that the researcher will be able to
proceed smoothly with the research activities
according to the time frame of the study.

Collate, Analyze, and
Interpret the Data
After gathering the
data, they are
collated, arranged,
and presented for
easy analysis and
interpretation.

Limitations or Weaknesses
of Case Study Method
1. The researcher may select convenient
cases, which are not typical for a case study.
2. The researcher may find difficulty
selecting the factors to be studied due to
different environmental settings and
sampling sizes.

3. Hypotheses cannot be tested due to small
sampling size and limited number of variables.
4.Reliable and genuine data may not be obtained
in some case studies due to limited primary
sources.

Experimental Methods of
Research

Several Reasons For Conducting
Experiments in a Natural Setting:
1. To test the external validity of
a laboratory findings.
2. To improve conditions under
which people live and work.

Experiment also
Involves…….

Manipulation of One or
More Variables which
includes the:
-Independent Variable
-Dependent Variable

Characteristics of a Good
Experiment
- Internal Validity
-Reliabililty
-Sensitivity
-External Validity

Internal Validity
-if the cause and effect is interpretable,
that is by manipulating the independent
variable, it can cause a change in
dependent variable.

Reliability
An experiment is
reliable if the obtained
difference is likely to be
found again and if the
experiment is to be
repeated.

Sensitivity
-an experiment is sensitive if such
experiment is likely to detect the effect
of an independent variable even when
that effect is a small one.

External Validity
-if the findings can be generalized to
individuals, settings,and conditions
beyond the scope of the particular
experiment.

Purpose of Conducting
Internship
- To provide empirical tests of
hypotheses derived from theories.
-experiments can be used to test the
effectiveness of treatments and program.

Two Conditions for an
Effective Experiment
-Experimental Control
-Random Assignment

Three Conditions of Control:
-Covariation

-Time Order
-Plausible Alternative Courses
