Q & A
What is the main purpose of descriptive research design?
-The main purpose of descriptive research design is to gather data from a relatively large number of cases to define the existing condition or phenomenon of a classified variable. It aims to describe trends, correlations, and categories by answering questions like what, how, when, and where.
Can you provide an example of a topic that uses descriptive research design?
-An example of a descriptive research design topic is 'A description of how parents feel about the K-12 curriculum.' This type of research focuses on describing the current or prevailing conditions related to the topic.
What is correlational research design used for?
-Correlational research design is used to define the degree of relationship between two or more variables using statistical data. It helps determine whether a relationship between variables is positive or negative.
What is an example of a topic using correlational research design?
-An example of a correlational research design topic is 'The relationship between number of sleep hours and academic performance.' This research investigates how the number of sleep hours may affect academic performance.
What distinguishes experimental research design from other designs?
-Experimental research design is characterized by the manipulation of an independent variable to determine its effect. Respondents are randomly assigned to treatment groups, and the research is often conducted in controlled laboratory settings.
Can you provide an example of experimental research design?
-An example of experimental research design is 'The effect of a video learning tool on academic performance.' In this case, the video learning tool is the independent variable being manipulated to observe its impact on academic outcomes.
What is causal-comparative research design?
-Causal-comparative research design explores possible causal relationships among variables that cannot be manipulated by the researcher. It often involves comparing two or more groups to determine the cause of differences in outcomes.
What is an example of causal-comparative research design?
-An example of causal-comparative research design is 'The effect of peer counseling and support groups on students' emotional condition.' This research compares groups to identify whether peer counseling or support groups influence emotional well-being.
What are the key differences between descriptive and correlational research designs?
-Descriptive research focuses on describing current or prevailing conditions, while correlational research examines the relationship between two or more variables. Descriptive research does not look for cause-and-effect, whereas correlational research looks at the strength and direction of relationships between variables.
How do experimental and causal-comparative research designs differ?
-Experimental research involves manipulating an independent variable and assigning subjects randomly to groups, while causal-comparative research compares existing groups without manipulation to find causal relationships. Experimental design seeks to control variables, whereas causal-comparative design observes natural differences.
Outlines
📊 Descriptive and Correlational Research Designs
This paragraph introduces the concept of research design in quantitative research, focusing on descriptive and correlational designs. Descriptive research aims to define existing conditions or phenomena without manipulating variables. It is used to identify trends, correlations, and variables. Examples include studying parents' feelings about the K-12 curriculum and analyzing the impact of a Filipino program. Correlational research design measures the degree of relationship between two or more variables using statistical data. It helps determine how one variable affects another, as illustrated by the example of the correlation between sleep hours and academic performance.
🔬 Experimental and Causal Comparative Research Designs
The second paragraph delves into experimental and causal comparative research designs. Experimental research involves manipulating an independent variable to observe its effect on a dependent variable, such as testing the efficacy of a vaccine. It typically takes place in a controlled environment like a laboratory, with subjects randomly assigned to treatments. Causal comparative research explores potential causal relationships among variables that cannot be manipulated, comparing at least two groups to determine the cause of pre-existing differences. Examples given include the impact of peer counseling on students' emotional conditions and whether attitudes toward math differ by gender.

hello marco almat in this video lesson
we will discuss the different research
design in quantitative research
so san bernardino research design is a
chapter two or nasa methodology nation
so after new methodology market anatomy
on research
non-descriptive research design it used
to gather data from relatively large
number of cases
and it defines the existing condition or
phenomenon of a classified variable
so as a descriptive research design case
identifying
trends
correlation and uh even variables and
categories
like what how when and where so manga
you says okay no research on design at
all which is the descriptive
to describe the current or prevailing
conditions
another is to take purposefully data
from respondents so i need my examples
and descriptive research design so
example topics or uh noped impact
arrange a descriptive research design
a description of how parents
feel about the k-12 curriculum
another example analyzing the impact of
the pantoid pamela filipino program
so again and descriptive research design
i
well uh he didn't exist him as a
hypothesis
after known
uh collection of data so after that in
my gathering data so petty time macaroni
and hypothesis done so
in descriptive a hindi nagi starts a
hypothesis
another research design is correlational
so it is
[Music]
is correlational research design so it
defines the degree of relationship
between two or more variables using
statistical data so
design and genomic
so like for example uh it's a
topic let's say for example correlation
between number of sleep hours and
academic performance
so dito
is a problem
de la luang viable which is the number
of sleep hours and the academic
performance so teeny ting nan kumar
relationship battalaga young number of
sleep arts du sama gigging academic
performance nice to jante so it is
relational research design so
correlational research design uses to
determine means the extent of how one
variable relates to another
and another it described how one viable
affects the other so detos a
correlational research design
magicking uh result no no
study malama it's either dating and mo
if they have positive
or merocilan negative correlation so
madeleines gamete
uh
instrument or noise statistical
treatment para magua nothing
or negative correlated assume person are
so
another example the correlational what
is the relationship between study time
and the exam score among senior high
school student so many time the long
variable then
the study time and the score of the exam
score so you're in the variable nathan
next is experimental so an experimental
matas
no it is
it's a research design
so
experimental research design is an
independent viable is manipulated to
determine the effect of manipulation
like for example
generation
medical area no let's say in vaccine and
develop the vaccine
effective or hindi so that is
experimental so in experimental research
design
your respondents modi in internet
and then kissing experimental research
design hindi language survey hindi
nagoya questionnaires
experimental research design true
laboratory
and of course in experimental research
design the subjects are randomly
assigned to experimental treatment so
take note your word randomly assign so
again an example nathan an independent
video learning tool its effect on
academic performance
so tinnitus or teeny ting nan
okay your independent video learning
tool or you
so another research design is the
coastal comparative it explore possible
causal relationship among variables that
cannot be manipulated by the researchers
so
at least two groups
uh since you are comparing the two
groups
or two or more groups eating them
so at least may
and the researcher attempts
to determine the cause
or the reason for
pre-existing difference in groups of
individuals
one of the characteristics of causal
comparative it investigates whether
there are differences
between two or more groups on the
phenomena so like for example the effect
of
peer counseling and support group one
student's emotional condition so another
example do attitudes toward math differ
by gender so it is into some
lagging clinic questions no
uh
angle
high school students so
pr tunil also quantitative research
still so maritime descriptive
correlational experimental and then
causal comparative
a right to summarize the quantitative
research design first is the descriptive
which is uh the main focus is to
describe characteristics
correlation studying relationship
between two variables
experimental manipulating condition and
studying effects and for causal
comparative comparing known groups to
determine
causality
