In this case, the number of hours of sunlight is the independent variable and
the height of the plant is the dependent variable
, because the change in the height depends on the hours of sunlight, not the other way around.
Is light a dependent or independent variable?
The independent variable is the amount of light
and the moth’s reaction is the dependent variable. In a study to determine the effect of temperature on plant pigmentation, the independent variable (cause) is the temperature, while the amount of pigment or color is the dependent variable (the effect).
Is sunlight an independent variable in science?
The independent variable is
the amount of sunlight each plant receives
. 2. In an experiment to test the effect a gasoline additive has on gas mileage in a car, the amount of additive per gallon is the independent variable. 3.
What would be the dependent variable?
The dependent variable is
the variable that is being measured or tested in an experiment
.1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
Is sunlight a controlled variable?
Each plant is exposed to an equal amount of sunlight, so
sunlight is the control variable
.
Is time an independent variable?
Time is
a common independent variable
, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
How do you control independent variables?
In a
controlled
experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.
How do you tell the difference between 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.
What is the difference between dependent and independent variable 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.
How do you explain independent variables to kids?
An independent variable is a variable that you can control. One way to explain it to a child is that it is
the variable that the child can change during the experiment
. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant receives.
Is water a dependent variable?
The dependent variable is usually what scientists measure in an experiment. … In this case, the
amount of water is the independent variable
because that is what you’re changing in the experiment: one seed gets a lot of water and the other seed only gets a little water.
What are the examples of 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.
What is the independent variable sunlight?
Independent variables are essential to scientific work and the scientific method. An independent variable in an experimental setup is the manipulated variable. In an experiment to test how the amount of sunlight affects the growth of radishes. The independent variable is
the amount of sunlight each plant receives.
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 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.
Is stress a dependent or independent variable?
Example: You are interested in how stress affects heart rate in humans.
Your independent variable would be the stress
and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
