Variable
An independent variable is a part of an experiment that might change due to the outcome not being a desired result. The person conducting an experiment about how a medicine might affect a person, might change the number of people tested to gain more insight into the results. The independent variable in that situation would be the number of test subjects.
just do the experiment... but i think so.
yes and it depends on..... Adults get confused on these questions too!!
You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.
false
It can, but need not, affect the outcome of the experiment variable.
Expiramental variable
If changes in one variable do not affect the outcome of another variable, then the second variable is independent. A variable that is not independent is dependent.
independent variable
independent variable
It is a relevant variable.
Extrinsic variables.
It depends on the experiment. Normally only one is tested at a time because they can affect the experiment. Variables are tested in a controlled experiment to see whether they affect the outcome and also how.
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
-conditions or events that could affect the dependent variable (outcome of an experiment) but do not, because they are held constant for for both the experimental and control group.
Definitely not.
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
