What are variables in research methodology

The goal of applied research is to improve the human condition.I appreciate the effort made in explaining the key variables with some relevant examples.How will you know that one variable may cause the other to behave in a certain way.II. Ethnography:- this type of research focuses on describing the culture of a group of people.Methods of Research. measuring the relation between two variables.Therefore, it is a must that you should be able to grasp thoroughly the meaning of variables and ways on how to measure them.

Qualitative research is collecting, analyzing and interpreting data by observing what people do and say.Statistical Conclusion Validity: Unfortunately, without a background in basic statistics, this type of validity is difficult to understand.My project topic is Extra judicial killings and involvement of military forces,how do i go about drawing my conceptual framework and what variables best suits Reply.

Correlational research: In general, correlational research examines the covariation of two or more variables.Identify another variable that you think is a possible cause and explain why you think it might be a cause.

First, every experiment must have at least two groups: an experimental and a control group.When a study uses pre-existing groups that are not naturally formed, the variable that is manipulated between the two groups is an independent variable (With the exception of no random assignment, the study looks similar in form to a true experiment).Qualitative research presents non-quantitative type of analysis.

There are many types of variable but the most important, for the vast majority of research methods,.I was considering to enroll in statistics course to equip me in my consultancy work (socio-economic studies), found this site very informative, I need to really study though.If our strata were gender, we would sample both men and women.

These two variable, smoking and lung disease were found to covary together.From these observations it may be possible to construct generalizations.For example, if you conduct a study looking at heart disease in men, can these results be generalized to women.The second reason to sample is that it may be impossible to test the entire population.Measures that were taken included heart rates before and after blood tests, ease of fluid intake, and self-report anxiety measures.

First, it is usually too costly to test the entire population.

The dependent variable is the one that the experimenter is measuring.

The Research process: an independent and dependent

The following examples of phenomena from a global to a local perspective.We can get that information from operating on a small sample of rats.After a few months of study, the researchers could then see if the wellness site had less absenteeism and lower health costs than the non-wellness site.Children were randomly assigned to either the treatment or the control condition.

Difference Between Independent and Dependent Variables Which of the above examples of variables are the independent and the dependent variables.The study demonstrated that the systematic preparation and support reduced the difficulties of being in the hospital for these kids.

The number of hours dedicated by parents in providing tutorial support.You do not start with a title but a review of literature first on a phenomenon you have observed.In many cases, extraneous variables are controlled for by the experimenter.An operational definition describes how the variables are measured and defined within the study.In modeling ecosystems, if either of the variables could influence the other, these are called feedback loops.However, while we know that the two variables covary - a relationship exists - we do not know if a causal relationship exists.

Thank you very much for this simple and clear clarification of the difference between dependent and independent variables Reply.

It is also by far the most biases sampling procedure as it is not random (not everyone in the population has an equal chance of being selected to participate in the study).When designing a study, a sampling procedure is also developed including the potential sampling frame.There are four types of validity that can be discussed in relation to research and statistics.

The explanation on DV and IV was simply fantastic. it helped defused the tension on my brain. thank you very much.As stated above, a sample consists of a subset of the population.Regression analysis is a quantitative research method which is used when the study involves modelling and analysing several variables.Do I have to depict the two variables within the topic of a thesis.Since your conceptual framework reflects your thesis, you need to state your argument as your guide in your study.

I, with all my experience in research, would not put the explanation in such a plain, understandable way. kudos.
