The temperature of water was measured at different depths of a pond.
Independent variable
– – depth of the water. Dependent variable – -temperature.
Is water a independent variable in an experiment?
An experiment usually has three kinds of variables:
independent
, dependent, and controlled. … For example, if you open a faucet (the independent variable), the quantity of water flowing (dependent variable) changes in response–you observe that the water flow increases.
What type of variable is the water?
The water is
the dependent variable
. If there is a cause and effect relationship between water and temperature, then the water will change with the temperature change.
How do you know if it is independent variable?
There are two types of variables-independent and dependent. … 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.
Is water independent 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.
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).
Is height a dependent or independent variable?
the average height of adults might give you a graph as shown below.
The independent variable is average height
. The dependent variable is weight. … For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.
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 dependent and control variables?
- Independent variable – the variable that is altered during a scientific experiment.
- Dependent variable – the variable being tested or measured during a scientific experiment.
- Controlled variable – a variable that is kept the same during a scientific experiment.
What are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example:
How long you sleep (independent variable) affects your test score
(dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
What are the 5 types of measurements?
Types of data measurement scales:
nominal, ordinal, interval, and ratio
.
What are the 5 types of variables?
- Independent variables. An independent variable is a singular characteristic that the other variables in your experiment cannot change. …
- Dependent variables. …
- Intervening variables. …
- Moderating variables. …
- Control variables. …
- Extraneous variables. …
- Quantitative variables. …
- Qualitative variables.
What type of variable is age?
In our medical example, age is an example of
a quantitative variable
because it can take on multiple numerical values. It also makes sense to think about it in numerical form; that is, a person can be 18 years old or 80 years old. Weight and height are also examples of quantitative variables.
How do you manipulate independent variables?
Again, to manipulate an independent variable means
to change its level systematically
so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.
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.
What is an independent variable in psychology example?
The independent variable is
the variable that is controlled and manipulated by the experimenter
. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the experimenter.
