The dependent variable should be specified in the quantitative design because the research idea is to construct a project that brings out the relationship between the two variables.

Maturation indicates that participants become older, wiser, more hungry and depressed. The effect being investigated may also change depending on the number of times the tests are conducted. The design of the outcome research first requires the researcher to identify the perspective on which the conclusion will be arrived.
