the control for multiple variables in a experiment
A type of experimental design in which a hypothesis is tested under carefully controlled conditions, and the control group is compared with the experimental group.
You need a control group which does not receive the experimental variable, you need an experimental group which receives the experimental variable. You need an experimental variable, and you need to keep everything else the same.
It involves assignment of subjects to experimental group and control group. it also involves subjecting the experimental group to experimental treatment. it can be defined as an "After the fact design". it is a form of design in which a particular characteristics of a given group is investigated so as to identify it anticidents.
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
The next car show will have an example of our experimental design.
A quasi-experimental design is a design that resembles and experimental design but does not have the key ingredient of random assignment. They involve selecting groups that are used to test a variable but with no random pre-selection process.

True experimental design is considered as the most accurate form of experimental research. The important factors that might affect the phenomena are completely controlled.
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."

Pre-experimental design is the most simple form of research design. A group or multiple of groups are observed to something that should cause change in them.
