What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
In an experiment the group that is exposed to the variable to be tested is called the?
control group
Who is group that is exposed to the variable to be tested is called the?
Experiments typically involve:1) Experimental group: the group of subjects exposed to the variable being tested.2) Control group: should be as identical as possible to the experimental group, but is deliberately not exposed to the experimental variable - this provides a baseline measure from which the effect of the variable can be determined.
What is the difference between a conrtol group and an experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the controlled variables on an experiment?
-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.
Does the experimental group test the dependent variable?
The effect on the dependent variable will be different in the experimental group than the control group, which is why you measure the dependant variable.

In an experiment a group that is identical to a control group except for one factor and that is compared with the control group?
a controlled experiment is an experiment that tests only one factor at a time by using a control group and experimental group
In an experiment the group that is exposed to the variable to be tested is called the?
control group
Why is a control group important to have in a experiment?
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
What is the different between a control group and an experimental group in an experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the difference between the control group and the experimental group in a controlled experiment?

What differs between the control group and an experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the difference of control group and the experimental group?
Experimental group has been exposed to the independent variable whereas the control group has not, and is often used to compare the experimental group's results against.
The group that is exposed to the variable to be tested is called the what?
Control
