2. Case study research as a strategy for
methodological exploration, according to FLYVBJERG
(2011) "has been around as long as recorded history".
Contemporary case study research is said to have its
origins in qualitative approaches to research in the
disciplines of anthropology, history, psychology, and
sociology (MERRIAM, 1998; SIMONS, 2009; STEWART,
2014).

4.  Survey reveals what is typical, average, or normal
against which the behavior or performance of an
individual can be judged or evaluated.
 The results of the survey may be used for prediction.
This is especially true in correlation studies or even
status studies.
 Survey makes possible the formulation of
generalizations because the sample has a high
degree of representativeness.

5.  Survey reveals problems for which timely remedial
measures may be instituted.
 It is easy to get respondents for a survey.
 The instruments for gathering data are easy to
determine, construct, validate, and administer. The
survey instruments are usually the interview schedule
as well as the questionnaire and they are very similar
if not the same in structure.

7.  Lack of manipulation over independent variables.
 One cannot progressively investigate one aspect
after another of the independent variable to get
closer to the real cause.
 Statistical devices are not always able to separate
the effects of several independent variables when
there is multivariable causation, especially when
two independent variables are themselves highly
associated.

8.  Survey approach yields a low degree of control or
there is no control at all over extraneous variables.
 The instrument for gathering data may lack validity,
reliability, or adequacy.

9. TYPES OF SURVEY TECHNIQUE OR APPROACH
Total population survey. The entire population is
involved in the survey.
Sample survey. Only a sample or portion of the
population is involved in the survey.
Social survey. The investigator researches on
the attitudes and behaviors of different groups of
people.

10. School survey. This is used to gather data for and
about schools and to assess educational achievement
and education itself.
Public opinion survey. This is used to gauge the
reactions of people towards certain issues or persons.
Poll survey. This is a survey in which the respondents
are asked if they are voting for a certain candidate in an
election. This survey is used to predict the chance of
winning of a certain candidate in an election.

11. Market survey. This is aimed at finding out what kinds of
people purchase which products, and how packaging,
advertising affect buying, prices, and so on. Allied to this
is the motivation survey in which the subjects are asked
why they purchase certain commodities.
Evaluation survey. The researcher looks back to see
what has been accomplished and, with a critical eye,
evaluates the results whether they are satisfactory or not,
with the end in view of making improvements.

12. Comparative survey. In this survey, the results from
two different groups, techniques, or procedures are
compared.
Short-term survey. In this survey, data are collected
over a period of weeks, months, or even years but the
period should be less than five years.
Long-term survey. Any survey conducted for more
than five years is a long-term survey.

13. Longitudinal survey. This is almost the same as the
long-term survey.
Cross-sectional survey. In this type of survey, several
groups in various stages of involvement are studied
simultaneously.
Job analysis survey. This provides information on the
general duties and responsibilities of workers, their
education, training, experiences, salaries, types of
knowledge and skills, and others that help administrators
or managers in setting up training programs and
recruitment policies.

14. Community survey. This survey provides information
on the general various aspects of the community:
health, employment, housing, education, economic
resources, delinquency, family, population, other social
problems, and so on.
Correlation study. This is a study that shows the
relationship between two or more variables, that is,
how a variable varies with another.
