When a researcher manipulates a variable to see what effect the manipulation has on another variable, the research design is an Experience.

Explanation:

When a researcher wants to know the effect of the experiment on an object, he must have relevant experience. This design can be stated based on experience, and the experience can only gain by experimenting on another object, which many people refer to as Hit and Trial.

We can say in other words, whether variations in sovereign variables affect differences in a secondary variable. Experiments hold pair of primary characteristics. The primary is that the researchers manipulate, either orderly vary, the level of the free variable.
