What is a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
In a controlled experiment what term is used to describe the many factors that might be different between the experiment and control groups?
Variables
Why an experiment must have control?
An experiment must have a control to show what would happen if no factors were changed.
The factor by which an experimental group differs?
In an experimental design comparing two groups in which one group gets one treatment and another group gets a second treatment, the experimental group is the group with the "different" treatment. The control is the "usual" treatment; the experimental group gets the "new" treatment. Of course, things get complicated with more complicated "experiments."
What factors must be controlled during an experiment?
The control is an object where you change nothing; you compare it to the thing that you test.
In a controlled experiment what term is used to describe the many factors that might be different between the experimental and control groups?

What is the purpose of using multiple control in an experiment?
To help you conclude that no uncontrolled factors significantly influenced your results. To help you determine that your experimental results are valid To help control for factors that aren't being tested but might affect results
What is a uncontrolled vairable?
* factors which are not considered in the experimental design * shouldn't have any effect on the experiment
Why an experiment must have control?
An experiment must have a control to show what would happen if no factors were changed.

A factor in a experiment that can change?
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
What does random assignment ensure?
Random assignment ensures that participants in an experiment have an equal chance of being assigned to different experimental conditions. This helps to control for potential biases and ensures that any differences in outcomes can be attributed to the treatment being tested rather than other factors.
What is a expiriment?
Where you control the variable factors that involve conducting the experiment.
What is the contolled and experimental group in an experiment?
Experimental control is a group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment It is also the standard of comparison. -Also, look for the following things: Experimenter Bias, History, Maturation, Instrumentation, Selection, Order, and Statistical regression. All of these should be questioned.
