Q2(Week 1) Flashcards
what is included in the research methodology?
the research design, respondents of the study, the sampling technique, research instrument, reliability and
validity, data collection, data
analysis and ethical considerations.
It is a systematic approach that a
researcher uses to conduct a
scientific study.
research design
It is a synchronization of identified
components and data resulting in
a plausible outcome.
research design
What is a quantitative research design?
used to examine the relationship
between variables by using
numbers and statistics to explain
and analyze their findings.
Four Types of
Quantitative Research Design
Descriptive Research Design
Correlational Research Design
True Experimental Research
Design
Quasi-experimental Research
Design
This experiment is designed just
like the true experiment design,
except that it does not use
randomized sample groups.
Quasi-experimental Research
Design
This is a method used to establish a cause and effect relationship
between two variables or among a group of variables. The independent variable is manipulated to observe the
effect on the dependent variable.
True Experimental Research
Design
This seeks to discover if two
variables are associated or
related in some way, using
statistical analysis while
observing the variable.
Correlational Research Design
it is intended
to describe the present status of a phenomenon. This type does not require a hypothesis to begin
with. These analyses are
generated from existing data.
Descriptive Research Design
What are research sample/
respondents/participants/subjects?
the persons whom
responses about the
research problem will be
drawn.
What is sampling?
Sampling is defined as measuring a small portion of
the population. The small portion or element who
are selected to participate or to be the subject of the
study is known as the sample.

sampling
Why we need sampling?
Sampling makes possible to study a large, heterogenous
population because in sampling only a small portion of
the population may be involved in the study.
Sampling
is for economy because it reduced the study population
to a reasonable size that expenses are greatly reduced.
Sampling is for speed because it is less time consuming
to gather data from a small sample. Sampling is for
accuracy since small portion of the population is
covered and it takes less time to finish the study
resulting to more valid and reliable result.
General Types of Sampling
Probability Sampling.
Non-Probability Sampling.
The sample is a proportion of
the population, and such
sample is selected from the
population by means of some
systematic way in which
every element of the
population has a chance of
being included in the sample.
This sampling is used usually
for quantitative studies.
