Experimental studies are based on the definition of the method followed by variables and controls according to the specific conditions of the phenomenon that is the focus of study in the educational process, and the study to work to observe all the changes resulting from the effects of this phenomenon,

1. Experimental studies are based primarily on clarifying the parameters of the scientific experiment through careful observation and experimentation.

2 - The opportunity to know the correct results and facts and the enactment of the necessary laws and know the right ways to reach the most point to work with the phenomenon to discover what is through the use of scientific experience.

3 - The value of empirical studies in applied science, based on the detection of the relationship between different phenomena and verify the hypotheses set by the researcher and that is through some scientific experiments to solve the problem

It is a way of gaining knowledge by means of direct and indirect observation or experience. Empiricism values such research more than other kinds. Empirical evidence can be analyzed quantitatively or qualitatively. Quantifying the evidence or making sense of it in qualitative form, a researcher can answer empirical questions, which should be clearly defined and answerable with the evidence collected. Research design varies by field and by the question being investigated. Many researchers combine qualitative and quantitative forms of analysis to better answer questions which cannot be studied in laboratory settings, particularly in the social sciences and in education.

It is real solution of issue. Watford for issue management

A study is the best solution to develop appropriate treatment in all fields and know the result before starting the experiment and overcoming the obstacles resulting from the experience ...

Thanks a lot Wahag Abass , M. A. A. Al- Fatlawi , Zainab A Makawi and Anjay kumar Mishra for your informative response

Empirical studies will dispel any misunderstandings or mere opinions about phenomena and the cause/effect relationship. In many fields of engineering rigorous mathematical modeling based on the physics of the situation is difficult. Thus scientists and engineers have resorted to collecting data under a variety of conditions and to find an empirical relationship among variables. The results available in the form of graphs and monographs are highly useful. Such correlations abound in fluid mechanics, hat and mass transfer, for example.
