Q & A
What is the difference between an independent variable and a dependent variable in a study?
-An independent variable is something that can be manipulated by the researcher, and it affects the dependent variable. The dependent variable is the outcome or effect that is influenced by other factors, including the independent variable.
Can you give an example of a dependent variable?
-A test score could be a dependent variable because it can change depending on several factors such as study habits, sleep, and hunger levels before the test.
What is the role of an independent variable in a study?
-The independent variable is something the researcher controls and manipulates to observe its effect on the dependent variable.
Can you provide an example of a study where social media usage is the independent variable?
-In a study determining the effects of social media on academic performance in mathematics, social media usage would be the independent variable, and academic performance would be the dependent variable.
What is a control variable in a study?
-A control variable is a special type of independent variable that is measured in a study because it potentially influences the dependent variable, and the researcher tries to keep it constant to isolate the effect of the independent variable.
What is the purpose of identifying confounding variables in a study?
-Confounding variables are factors that are not measured or observed in a study but could affect the dependent variable. Identifying them helps to ensure that the results are not biased by these unaccounted factors.
Can you provide an example of a confounding variable in the context of climate change?
-In the context of climate change, possible confounding variables could include sea level temperature, the amount of carbon emissions, and the amount of rainfall.
What is the role of a confounding variable in the relationship between study time and exam score?
-A confounding variable in this context could be the student's prior knowledge or learning style, which might affect the exam score independently of the study time.
How does the concept of dependent and independent variables apply to correlational research?
-In correlational research, the relationship between variables is examined without necessarily implying causation. The independent variable is the one being correlated with the dependent variable to see if there is a relationship.
Can you give an example of a correlational research question involving gender and attitudes towards music piracy?
-A correlational research question could be 'What is the relationship between gender and attitudes towards music piracy among adolescents?' Here, gender would be the independent variable, and attitudes towards music piracy would be the dependent variable.
What is the significance of understanding the difference between dependent and independent variables in research?
-Understanding the difference is crucial for designing experiments and studies effectively. It helps researchers determine what they can manipulate to test hypotheses and what they expect to observe as outcomes.
Outlines
π Understanding Dependent and Independent Variables
This paragraph introduces the concept of dependent and independent variables in research. Dependent variables are those that change in response to other factors and are the focus of the study, such as test scores which can vary based on study habits, sleep, and other factors. Independent variables, on the other hand, are those that can be controlled or manipulated by the researcher and are used to influence the dependent variable. Examples given include the impact of social media on academic performance and the correlation between kilowatts used and the electricity bill. The paragraph also touches on the idea that sometimes independent variables cannot be manipulated, and it introduces the concept of correlational research with examples relating to gender attitudes towards music piracy among adolescents and the relationship between study time and exam scores.
π Exploring Control and Confounding Variables in Research
The second paragraph delves into the role of control variables and confounding variables in research studies. Control variables are measured to account for their potential influence on the dependent variable, ensuring the study's validity. Confounding variables, however, are not measured or observed and can affect the outcome. The paragraph provides examples of variables related to climate change, crime and violence, and poor student performance in college. It also lists specific factors such as sea level temperature, carbon emissions, the number of attempted murders, prisoners, crime victims, law enforcers, and the number of kidnapping accidents as potential variables in these contexts. The paragraph concludes by encouraging viewers to like, subscribe, and stay updated for more educational content.

hello marco almad in this video lesson
we will discuss the independent and
dependent variables
so when say dependent variables depends
on other variables or factors it is
something that is influenced and
affected so ibiza b and pakistan be not
independent variable it is the effect or
the outcome so dependent variables are
what researchers are interested in they
depend on the
other factors
or for example a test score
could be dependent variable because it
could change depending on several
factors such as how much is studied how
much you sleep you get right before you
talk the test or even how hungry you
were when you top it so
again dependent variables into your
outcome or effect
depending on the factors or some
variables
hand
independent variables affects the
dependent variables it is something you
have control over one which you can
choose and manipulate however in some
cases you may not be able to manipulate
the independent variables so when you
say independent variables
or the reason behind changes
so s
so for example the researcher wants to
determine the effects of use of social
media in the academic performance of
students in mathematics
so what will be the independent viable
and dependent variable
of course your independent variable
nathan union use of social media and the
independent net and new academic
performance
and social media
academic performance
another example so independent variables
the number of are studying for a test
and then the test scores
so test score depends on the number of
rs studying for a test another
so let's say independent viable latin is
the kilowatts used in a household and
then the dependent variable is the
electricity bill
so electricity bill depends on the
kilowatts used in a household
so examples of correlational research
so what is the relationship between
gender and attitudes toward music
viruses among adolescents
independent independent viable
independent and dependent viable so
again what is the relationship between
gender and attitudes toward music's
piracy among adolescents
so what will be independent fireballs at
the independent viable net end so
independent variable nation is the
gender
and the dependent variables it's the
attitudes toward music viruses
another example what is the relationship
between the study time and exam score
among senior high school students
know about test scores and then
uh young's study time so i'm normally
independent variable nathan of course
that
sony making independent variable jump in
the study time and the dependent
variable is the exam score so i hope
naga pagoda
study or research
outcome or effect and then you
independent variable amount shy on costs
or reason and changes
then
so
many times
other kinds of variables the control
variables is a special type of
independent that are measured in a study
because they
potentially influence the dependent
variables and of course we have
confounding variables those that are not
actually measured or observed in a study
so according to regul of 2012 cited by
preto it gives advance this example of
variables
like for example the climate change
so what are the possible variables for
climate change
sea level temperature
the amount of carbon emission the amount
of rainfall
and
for
crime and violence on streets so what
are the possible variables animapedim
variables not indita number abrupt is
number of attempted martyrs
number of prisoners
number of crime victims
and number of law enforcers
also the number of kidnapping accidents
and for
poor performance of students in college
in trans exam so and
breading variables not in
or factors the entrance exam score and
pedinating quantify n
number of hours devoted for uh to study
student teacher race also is
a college entrance exam
number of students in the class daliana
