How to identify research Variables?

There are different types of research Variables in scientific research and academic studies, the Variables in scientific research are what goes on in the field of scientific research and study, in order to identifying research Variables/formulating research Variables, the researcher collects the scientific material for the study and its theoretical framework, for each scientific study, whether educational study or academic study.

 Definition of Research Variables 

Research Variables can be defined as: "A set of stimuli and responses that interact with each other to create the kind of relationships that the researcher wants to experience. It is well known that the characteristics of Variables vary from one community to another. Variables are those characteristics that can be changed from one individual to another in society".

 Types of Research Variables 

Identifying research Variables/formulating research Variables is of great importance, where a researcher in the process of identifying research Variables/formulating research Variables should consider that there are different types of Variables. In order to identifying research Variables/formulating research Variables, the researcher should consider the following types of Variables:

• Independent Variable:

The independent Variable is the Variable that affects other Variables and is not affected by them, the independent Variable is what the researcher selected from quantifiable qualitative or qualitative qualities to influence all or some of the other Variables in the scientific study and linked to a relationship with the subject of the research.

The researcher seeks to explain the relationships and the effects between independent Variables and dependent Variables, and the scientific researcher deals with independent Variables set of controls and systematic research steps, there are differences between dependent Variables and independent Variables, and exploits the scientific researcher absence, or quantitative differences between Variables and between the independent Variables, the purpose in the end is the researcher's ability to adjust the independent Variables and define search Variables and identifying research Variables/formulating research Variables in the research or study-based preparation.

• The dependent Variable:

Another dimension in identifying research Variables/formulating research Variables is the dependent Variables are Variables that follow independent Variables, and the effect of independent Variables falls on dependent Variables, it is very easy to measure the effects on dependent Variables, and dependent Variables in the problem of research or scientific research as a whole, and the relationship between independent Variables and dependent Variables. Affiliates in experimental or educational scientific research is what distinguishes between the types of Variables and any of them dependent Variable and any of them independent Variable that has the effect and intended treatment.

• Internal Variables or intermediate Variables:

Another dimension in identifying research Variables/formulating research Variables is the intermediate Variable in scientific research is one of the types of Variables with secondary role in the research, which made relationship and size between dependent and independent Variables. We find the intermediate Variable acts as a mediator between the independent Variable and the dependent Variable, the researcher chooses to determine the intermediate Variable in order to help pass the effects on the dependent Variables, or participate in monitoring the effects and relationships between the dependent Variables and intermediate Variables.

• Control Variables:

The types of Variables in scientific research are quantitative and qualitative Variables, dependent Variables and independent Variables, intermediate Variables and other Variables. The control Variable is done through the need to control the experiment in experimental scientific research, and taxonomic Variables are judged in the research and experiment if they are part of the experimental framework of the research experiment, reduce the effects of the control Variables during the experiment needs to classify the Variables and reach the real effect of the Variables.

 The difference between the types of research Variables in scientific research 

While identifying research Variables/formulating research Variables, finding the difference between the types of Variables in the research is not complicated or difficult, but it can be deduced with ease and simplicity, where the types of Variables are presented and clarified and through these types are deduced the difference between the Variables in scientific research, is the fundamental difference between Variables and distinctive. It is the type of relationship between those Variables, where independent Variables are the role of influential in the dependent Variables and subject to this effect.

The academic studies have a set of independent Variables and dependent Variables. Some scientific research needs more than one dependent Variable and more than one independent Variable, in addition to intermediate Variables and monitor their impact in the experiment, and some types of scientific research in the types of limited science. 

The types of Variables between dependent Variables and intermediate Variables and independent Variables and control Variables for all the Variables in the study, and that the researcher is the creator of those Variables by identifying the previous problem of the study and its intended topic of research and access to results by the researcher himself and monitored during the work on the preparation of the theoretical framework for research through writing and drawing the network of relationships for Variables in the study based on the preparation, and the multiplicity of independent Variables and dependent Variables in the study. 

Although it indicates the ability of the scientific researcher on the monitoring and experience and to identify research Variables and the formulation of search Variables and determine the relationships and influences between Variables, but it needs a lot of work from the researcher, and misses the researcher when not control his studies and size with the specific time plan in his research.
