A variable
is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment.
What is the measurable factor in an experiment called?
Explanation: The
dependent variable
depends on the independent variable. The independent variable is independent of all other factors in the experiment, and is graphed on the x-axis.
What is the factor being measured in an experiment?
Hence In an experiment, the factor that we measure is called
the independent variable
.
What is an independent variable in an experiment?
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.
Which question Cannot be answered by an experiment?
Questions that cannot be answered through scientific investigation are those that
relate to personal preference
, moral values, the supernatural, or unmeasurable phenomena.
What are 3 control variables?
An experiment usually has three kinds of variables:
independent, dependent, and controlled
.
What is the responding variable in an experiment?
A responding variable is
something that “responds” to changes you make in an experiment
. … The changes in an experiment are made to the independent variable (also called the manipulated variable); the responses that happen as a result of those deliberate changes are the responding variables.
How do you identify variables in an experiment?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you
change
, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
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.
How do you find the independent variable in an experiment?
The independent variable always goes on the x-axis, or the horizontal axis
. The dependent variable goes on the y-axis, or vertical axis. As you can see, this is a graph showing how the number of hours a student studies affects the score she got on an exam.
How do you identify independent and dependent variables?
The dependent variable is the one that
depends on the value of some other number
. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.

What is a controlled variable example?
Examples of Controlled Variables
Temperature is
a much common type of controlled variable. Because if the temperature is held constant during an experiment, it is controlled. Some other examples of controlled variables could be the amount of light or constant humidity or duration of an experiment etc.
