The document discusses the methodology of quantitative research, emphasizing the use of scientifically collected data to derive objective results and establish cause-and-effect relationships. It highlights the importance of large sample sizes for credible findings and introduces Sir Jonel Corpuz's research on community residents' knowledge, attitudes, and skills regarding local government services in Lebak, with specifics on sample distribution among barangays. Statistical formulas such as Cochran's are mentioned for determining sample size and ensuring reliable data analysis.

1. This type of research uses scientifically
collected and statistically analyzed data
to investigate observable phenomena.

2. Data gathering and analysis of results are
done accurately, objectively, and are
unaffected by the researcher’s intuition
and personal guesses.

3. The use of a statistical tools gives way for
a less time- consuming data analysis.

4. To obtain more meaningful statistical
result, the data must come from a large
sample size.

5. Data taken from a sample can be applied
to the population if sampling is done
accordingly, i.e., sufficient size and random
samples were taken.

6. Depending on the type of data needed,
collection can be quick and easy.
Quantitative research uses standardized
research instruments that allow the
researcher to

7. Data is taken and analyzed objectively
from a sample as a representative of the
population, making it more credible and
reliable for policymaking and decision
making.

8. The Quantitative method can be repeated
to verify findings enhancing its validity,
free from false or immature conclusions.

9. It is used to establish the cause-and-
effect relationship of variables.

10. It is used to establish the cause-and-
effect relationship of two or more
variables.

11. It is used to investigate a possible
relationship between previous events
and present conditions.

12. It identifies the relationship between
variables. Data is collected by
observation since it does not consider
the cause and effect,

13. It is used to describe a particular
phenomenon by observing it as it
occurs in nature. There is no
experimental manipulation, and the
researcher does not start with a
hypothesis.

14. The type of research that is using
words, images, or transcripts taken
from a small sample.

15. The type of research that is
generalizable to the population and
uses large sample size to produce
accurate and reliable data.

16. • Sample Size – Using the Cochran’s Formula. 5 points each.
Sir Jonel Corpuz will be conducting his research on the knowledge, attitudes, and skills of the community
residents about services of the local government in the Municipality of Lebak. In his research, a total 15,000
population size is identified and distributed to 7 barangays as follows:
A. 2,489 Respondents
B. 3,350 Respondents
C. 1,570 Respondents
D. 2,670 Respondents
E. 1,380 Respondents
F. 580 Respondents
G. 2,961 Respondents
Given: First Step
n0=1.962(0.5)(0.5)(0.5)2
=3.84160.5)(0.5(0.05)2
=3.8416 (0.25)(0.05)2
=0.96040.25
=384.16
Second Step: Compute the final Sample
Size using the Cochran’s Formula.
