Answer: An independent variable is exactly what it sounds like. It is
a variable that stands alone and isn’t changed by the other variables you are trying to measure
. For example, someone’s age might be an independent variable.
What are dependent and independent variables in research?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. … The dependent variable
is the variable being tested and measured in an experiment
, and is ‘dependent’ on the independent variable.
What is an independent variable in a research study?
The independent variable (IV) is the
characteristic of a psychology experiment that is manipulated or changed by researchers
, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What is dependent and independent variable in Research example?
In a study to determine whether how long a student sleeps affects test scores,
the independent variable is the length of time spent sleeping
while the dependent variable is the test score. … The independent variable in your experiment would be the brand of paper towel.
What are the 3 independent variables?
In this sense, some common independent variables are
time, space, density, mass, fluid flow rate
, and previous values of some observed value of interest (e.g. human population size) to predict future values (the dependent variable).
What is an example of an independent variable?
It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example,
someone’s age might
be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
Which is the dependent variable?
The dependent variable is
the variable that is being measured or tested in an experiment
. … The dependent variable is dubbed dependent because it is thought to depend in some way on the variations of the independent variable.
How do you identify independent and dependent variables?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an
experiment
, you manipulate the independent variable and measure the outcome in the dependent variable.
Can time be a dependent variable?
Time is always the independent variable
. The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable).
How do you know if a variable is independent?
You can tell if two random variables are independent
by looking at their individual probabilities
. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.
What are the 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables:
independent, dependent, and controlled
.
What is a sentence for dependent variable?
Two multiple regression analyses were performed with each contraceptive measure as a dependent variable. The dependent variable
here was equal to 1 if the women had ever used a medical method and zero otherwise
.
What is dependent and independent variable in qualitative research?
The independent variable is the variable that is being manipulated, or the one that varies. It is sometimes called the ‘predictor’ or ‘treatment’ variable. The
dependent variable is the outcome (or response) variable
.
Is a treatment an independent variable?
When a researcher gives an active medication to one group of people and a placebo, or inactive medication, to another group of people, the independent variable is
the medication treatment
. Each person’s response to the active medication or placebo is called the dependent variable.
Is height an independent variable?
In this study, time is the independent variable and
height is the dependent variable
. Answer 5: When you make a graph of something, the independent variable is on the X-axis, the horizontal line, and the dependent variable is on the Y-axis, the vertical line.
What are levels of an independent variable?
If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels:
experimental and control
. If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels.
