Thank you.

1. Ms. Ma. Irene G. Gonzales, LPT

2. Emphasizes on objective
measurements
Emphasizes on statistical,
mathematical or numerical
analysis of data

Education with SPSS. 2nd edition. London: SAGE Publications, 2010.

4. Data are collected through
polls, surveys,
questionnaires, or by
manipulating pre-existing
statistical data using
computational techniques.

8. Focuses on gathering
numerical data and
generalizing it across groups
of people or to explain a
particular phenomenon.

9. It is a systematic empirical
investigation of any
phenomena via statistical,
mathematical, or
computational techniques.

10. a formal, objective,
systematic process for
obtaining quantifiable
information about the world.

11. presented in numerical
form, and analyzed
through the use of
statistics;

12. Data is gathered using
STRUCTURED research
instruments.
Results are based on
larger sample sizes.

13. Can be replicated
or repeated, given
its high reliability.

14. Has a CLEARLY defined
research question
All aspects of the study
are CAREFULLY designed

15. Data are in the form of
numbers and statistics,
often arranged in tables,
charts, figures, or other
non-textual forms.

17. A DESCRIPTIVE STUDY is governed by
the following rules:
subjects are generally measured ONCE;
the intention is to only establish
ASSOCIATIONS between variables; and
the study may include a sample
population of hundreds or thousands of
subjects.

18. Project can be used to
generalize concepts more
widely, predict future
results, or investigate
causal relationships.

19. Researcher uses tools,
such as questionnaires or
computer software, to
collect numerical data

20. An EXPERIMENTAL DESIGN includes
subjects measured BEFORE and AFTER a
particular treatment, the sample
population may be VERY SMALL and
purposefully chosen, and it is intended
to establish causality between
variables.

21. DESCRIPTIVE RESEARCH DESIGN
Establishes associations between
variables
EXPERIMENTAL RESEARCH
DESIGN
Establishes causality

22. 1) Quantitative data is more
efficient and able to test
hypotheses, but may miss
contextual detail.

23. 2) Uses a static approach
and so employs an
inflexible process of
discovery.

24. 3) The development of standard
questions by researchers can lead to
"structural bias" and false
representation, where the data
actually reflects the view of the
researcher instead of the
participating subject.

25. 4) Results provide less
detail on behavior,
attitudes, and
motivation.

26. 5) Researcher may collect a
much narrower and
sometimes superficial
dataset;

27. 7) The research is often carried out in an
unnatural, artificial environment so that
a level of control can be applied to the
exercise. This level of control might not
normally be in place in the real world
thus yielding "laboratory results" as
opposed to "real world results".

28. 6) Results are limited as they
provide numerical descriptions
rather than detailed narrative
and generally provide less
elaborate accounts of human
perception.

29. 1) Allows for a BROADER STUDY.
involving a greater number of
subjects; and
enhancing the generalization of the
results.

30. 3) Applying WELL ESTABLISHED
STANDARDS
the research can be replicated,
and then analyzed and compared
with similar studies;

31. 2) Allows for GREATER OBJECTIVITY and
ACCURACY of results.
provides summaries of data that support
generalizations about the phenomenon under study
involves few variables and many cases
employs prescribed procedures to ensure validity
and reliability

32. 4) You can SUMMARIZE vast
sources of information and
make comparisons across
categories and over time.

33. 5) Personal bias can be
AVOIDED by keeping a
'distance' from participating
subjects and using accepted
computational techniques.
