What are variables in research methodology

Identify a third variable that you think is a possible consequence of your first variable and why you think it might be a consequence. (In other words, you need to identify three variables—A, B, and C.What then are variables and how do you use variables in your study.

Paper: Independent and Dependent Variables. the research problem.Examples of issues or problems that would threaten statistical conclusion validity would be random heterogeneity of the research subjects (the subjects represent a diverse group - this increases statistical error) and small sample size (more difficult to find meaningful relationships with a small number of subjects).SimplyEducate.me is accelerated by CDN77, a content delivery network.Be aware that this represents a cursory discussion of the concept of validity.Notice in the above examples of variables that all of them can be counted or measured using a scale.When the study includes naturally formed groups, the variable under study is a subject variable.A clinical trial is defined as a carefully designed experiment that seeks to determine the clinical efficacy of a new treatment or drug.My project topic is Extra judicial killings and involvement of military forces,how do i go about drawing my theoritical framework and what variables best suits Reply.

Marketing research and market research are the applied research.Quasi-Experiments: Quasi-experiments are very similar to true experiments but use naturally formed or pre-existing groups.

As no random assignment exists in a quasi-experiment, no causal statements can be made based on the results of the study.

Specific Research Question or Hypothesis Method and Design 17Results 17.Because quantitative research is rooted in the scientific method,.

Now I understand what variable means, as well as the difference between independent and dependent variable.The following examples of phenomena from a global to a local perspective.The point is that there are many differences between the groups that we can not control that could account for differences in our dependent measures.If these can be explained with good examples especially in social researches, then a ot will have been done.

Quantitative research - Wikipedia

It focuses on analysis and solving social and real life problems.

Research Methods. T. his chapter focuses on research designs commonly used when conducting. quantitative research studies. between variables,.For me you simplified it when you said Independent variable is the cause, I just say thank you. Reply.A key concept relevant to a discussion of research methodology is that of validity.

Thank you for visiting SimplyEducate.me and reading the articles.The control group provides us with the basis to make comparisons The independent variable in this study was the presence or absence of the systematic preparation program.As I was reading the climate change sample, I was asking myself where are the DV and IV, and then whether the temperature would be listed under the DV or IV.Each type of validity has many threats which can pose a problem in a research study.When a number of researchers use the same operational definition to measure a variable and achieve.

For example, in the first phenomenon of climate change, temperature (independent variable) may influence sea level (dependent variable).Exploratory research 10.Historical research 11.conclusion oriented research 12.case study research 13.short term research.If a difference is found between the pretest and posttest, it might be due to the experimental treatment but it might also be due to any other event that subjects experienced between the two times of testing (for example, a historical event, a change in weather, etc.).I really appreciate your efforts and your way of explaining it.The corresponding list of variables is given to provide a clear illustration of how complex phenomena can be broken down into manageable pieces for better understanding and to subject the phenomena to research.There are many types of variable but the most important, for the vast majority of research methods,.Not logged in Discussion for this IP address Contributions Create account Log in.Variables Variables Anything in the experiment that could be changed and affect the results of the investigation is a variable.

II. Ethnography:- this type of research focuses on describing the culture of a group of people.

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

Example given is temperature being the IV and sea level being the DV.In such cases, the experimenter will note the values of these extraneous variables so this impact on the results can be controlled for.Before we go further into the reasons why, let us first discuss what differentiates between a population and a sample.

Failure to understand the meaning and the usefulness of variables in your study will prevent you from doing good research.Also, avoid hypotheses you know (for certain) are true or hypotheses that are necessarily true.Just as including multiple dependent variables in the same experiment allows one to answer more research.
