Variables research variable definition are important concepts in research contexts. Research students need to have a basic understanding regarding the meaning of variables research variable definition in research and the types of research variables research variable definition so in this presentation. We will discuss the general meaning of research variables research variable definition in its various types. So first of all what is a variable variable in this general meaning a actually refers to something that changes something that is not fixed or constant or something that can have more than one values um generally in the research context variables research variable definition can be considered as attributes and or qualities of natural and or social phenomena which means concepts that can have more than one values in the research context in the particular research context in which these variables research variable definition have been used now in other words we can also say that variables research variable definition generally represents attributes or characteristics or qualities that are shared by a group of research participants or a set of research situations or sites or phenomena examples of research variables research variable definition um include gender so gender can be an available in a social science research or even in natural science research ability similarly intelligence can be a very variable color weight style and so on. There are numerous other examples of variables research variable definition that we used in research in social and natural contexts. Now generally variables research variable definition are associated with quantitative studies experimental research or quasi experimental studies and especially studies where there is. There is the aim of which is actually exploration of relations between phenomena between variables research variable definition both in natural and social sciences um manipulation and changes in the values of variables research variable definition basically helps the researchers in understanding the interaction of these variables research variable definition or the interaction of the factors or the constructs related to natural and social phenomena example of this of trying to find a relationship between two social phenomena is effect of teaching method for example on academic performance of students.
Now here we have two main variables research variable definition. Um teaching method is one variable and academic performance is is the other variable the phenomena from which we have taken these variables research variable definition for our research is education or teaching learning or you can say pedagogy so this is an example from from social sciences related to how we actually explore the relationship of variables research variable definition in research context. Now there are certain types of variables research variable definition. Um and here we are restricting. Ourselves to the main types of variables research variable definition so generally variables research variable definition have been categorized in several ways in several types and these the main types include qualitative or categorical variables research variable definition quantitative or numerical variables research variable definition independent variables research variable definition dependent variables research variable definition and extraneous variables research variable definition. Now what are qualitative or categorical variables research variable definition categorical or qualitative. Variables research variable definition are variables research variable definition that represent qualities so qualities of the phenomena or of the elements that we are studying in our research. For example personality type could be a quality that could be a variable in a particular study related to the study of personality or the relationship of personality with some other phenomena such as such as the level of confidence or maybe leadership similarly gender color belief nature etc. So these are some of the exams some some examples of what qualitative or categorical variables research variable definition. And as you can see that each of these variables research variable definition actually represent certain quality then quantitative or numerical variables research variable definition are variables research variable definition that represent quantitative or numerical attributes of the research participants or the research sites or phenomena and examples are for example marks. Students marks um age in terms of years or months or days etc class strength or the number of students in the class family size and salary etc so these are examples of quantitative or numeric variables research variable definition. Now the main types of variables research variable definition also include the most important types include independent variables research variable definition. So what are independent. Variables research variable definition generally the concept of independent variables research variable definition.
Independent variables research variable definition relate to experimental studies. Independent variables research variable definition are basically controlled variables research variable definition that are controlled or manipulated or changes are made to these variables research variable definition to see their possible effects on other variables research variable definition that are actually dependent variable. So what happens. Is that changes in other dependent. Variables research variable definition are basically attributed to or deemed to have been caused by the manipulation of the independent variables research variable definition for example. The effect of teaching methods on students academic achievement. So here the teaching method is can be taken as independent variable and the academic achievement of students can be taken as dependent variable and so the manipulation or the change in the independent variable. That is the teaching method might have consequences for or effect on the dependent variable in terms of students academic achievement. The main types of variables research variable definition also include dependent variable so as we already have mentioned independent variable. The dependent variables research variable definition are again is in line with independent variables research variable definition. Dependent variables research variable definition are used in experimental. Generally in experimental or relational studies and dependent variables research variable definition are deemed to have been caused by or changed by manipulation or control of the independent variables research variable definition. So we can say. These are the outcomes or changes in the dependent variables research variable definition or outcomes or effects of the changes or manipulation of independent variables research variable definition dependent. Variables research variable definition are generally we can say the effect of the independent variables research variable definition uh and so the independent variables research variable definition are the cause so again to take the same example effect of teaching method on students academic achievement so here the dependent variable is students academic achievement. Besides this the main types of variables research variable definition also include extraneous and confounding variables research variable definition extraneous. Variables research variable definition are basically variables research variable definition that are not investigated or that is actually investigation of future exploration of which is not the main aim of the research that we are conducting but these may affect the dependent variables research variable definition for example in this example effect of teaching methods on students academic achievement the extraneous variable could be students level of involvement or readiness so although we are exploring the effect of teaching method on academic achievement but the extraneous variable is here could be one of the extraneous variables research variable definition there.
Obviously there could be other extraneous variables research variable definition as well so one of those could be the student’s involvement or readiness. Maybe it is the environment inside the class or outside the class that could have affected the dependent variable that is academic achievement so such variables research variable definition are called extraneous variables research variable definition and so experimental. Researchers need to be vigilant regarding the the effect of such variables research variable definition in order to have more nuanced and deeper and more realistic understanding of the impact of variables research variable definition. Then confounding variables research variable definition are is another category. Or some some say a subset of extraneous variables research variable definition that may affect both the dependent or and independent variables research variable definition so for example the effect of teachers level of preparation or experience on teaching method which itself is in has been taken as an independent variable and then as well as on students academic achievement and again this might have might have impact on students academic achievement. So here we can see that the confounding variable that is the teacher’s level of preparation or experience has might have an effect both on the independent variable. That is the teaching method. The teachers use as well as the students academic achievement.
