Provide examples of experimental and nonexperimental research design. contrast the levels of control applied to each.

The two most commonly used designs for research studies are non-experimental and experimental.

The correlational and descriptive designs of research are considered and referred as non-experimental designs.

In non-experimental designs focus on examining variables as they naturally occur in environments and not in the implementation of treatment by the researcher.

On account of their capacity to decide causation, experimental designs are the highest quality level for research in medication, science, and sociology and so on.

In experimental design, researchers use random assignment and they manipulate an independent variable around a controlled variable. A true experimental design there must be randomization, a control group and manipulation of a variable when examining the direct cause or predicted relationships between variables.
