What else can I help you with?
Which term describes a type of independent variable used to compare differences in dependent varables?
experimental control
Why is experimental control needed in experiments?
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
How does the control setup in an experiment differ from the other setups in the same experiment?
EXPERIMENTAL SET UP * involves the set up that will allow you to investigate what you are interested to know. CONTROL SET UP * involves a set up that is exactly the same as the experimental, except the factor that you hypothesis to influence the results.

Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.
What is the relationship between Control and experimental groups?
control groups are those which you keep constant you don't do anything to them and experimental groups are the ones which you are adding something to it to see what happens
In an experiment the group that is exposed to the variable to be tested is called the?
control group
What is the difference between a control groups and experimental groups?
The control is a group that is held constant and is not experimented with, The experimental group is the group that is experimented with
What is a standard of comparison?
