The independent variable is the variable that the researcher manipulates or controls in an experimental design in order to observe its effect on the dependent variable.
The variable setup in an experiment is called the experimental design. This design includes all the factors and conditions that are manipulated or controlled in the experiment to test the research hypothesis.
Observed results are less likely to be affected by random chance.

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.

yes
Pre-experimental research designs are research designs that are characterized by a lack of random selection and assignment.
