What are variables in research methodology

For example, if I am a researcher studying patient satisfaction with emergency room care, I may potentially include the same patient more than once in my study.How will you know that one variable may cause the other to behave in a certain way.The hypothesis was that such preparation would reduce the amount of psychological upset and increase the amount of cooperation among thee young patients.If you know about these kinds of variables then you are free to share them here.If these can be explained with good examples especially in social researches, then a ot will have been done.For example, if my population consists of all individuals living in a particular city and I use the phone directory as my sampling frame or list, I will miss individuals with unlisted numbers or who can not afford a phone.For example, if you conduct a study looking at heart disease in men, can these results be generalized to women.

I was going to ask that question but I am glad that Gabe asked it and you answered it perfectly.Research is defined as a careful,. valid and variable, critical.Extraneous and Confounding Variables It is important to note that the independent and dependent variables are not the only variables present in many experiments.You do not start with a title but a review of literature first on a phenomenon you have observed.Find a social trend or behavior that is interesting and start from there.The dependent variable consisted of the heart rates, fluid intake, and anxiety measures.Each of the four types of validity will be briefly defined and described below.

Research and Methodology

Thank you, I am struggling with trying to develop a conceptual framework for my future dissertation, this article was a lot easier to understand than my text books.

For example, in our imaginary experiment on the effects of sleep deprivation on test performance, we would need to create very specific operational definitions for our two variables.Situational Variables: These extraneous variables are related to things in the environment that may impact how each participant responds.A theoretical list (an actual list may not exist) of individuals or elements who make up a population is called a sampling frame.Literature Review on Research Methodology for Social. as reflected by the operationalization of variables,.

Increased temperature will cause expansion of water in the sea.A clinical trial is defined as a carefully designed experiment that seeks to determine the clinical efficacy of a new treatment or drug.Correlational research is often conducted as exploratory or beginning research.

Research Variables | Dependent And Independent Variables

In this experiment, it would make sense to have as few of people rating the patients as possible.For example, a psychological case study would entail extensive notes based on observations of and interviews with the client.

Understanding what variables mean is crucial in writing your thesis proposal because you will need these in constructing your conceptual framework.Since your conceptual framework reflects your thesis, you need to state your argument as your guide in your study.The nature of this type of research is exploratory and open ended.You may read my post about conceptual framework and its relation to theoretical framework here.

Applied research can be further classified as problem oriented and problem solving research.What then are variables and how do you use variables in your study.What if there are more than the independent and dependent variable.You need to define your variable, as this article defines it.As you can see from the discussion above, one can not make a simple cause and effect statement concerning neurotransmitter levels and depression based on correlational research.As such, it is often conducted with the support of some financing agency like the national government, public corporation, world bank, UNICEF, UGC, Etc.The results are again restricted due to the quasi-correlational nature of the study.

In other words, statistics are not numbers that just appear out of nowhere.To understand the use of statistics, one needs to know a little bit about experimental design or how a researcher conducts investigations.For example, if a participant is taking a test in a chilly room, the temperature would be considered an extraneous variable.During their hospitalization the treatment group received the special program and the control group did not.In a stratified sample, we sample either proportionately or equally to represent various strata or subpopulations.For a comprehensive discussion of the four types of validity, the threats associated with each type of validity, and additional validity issues see Cook and Campbell (1979).Qualitative research is collecting, analyzing and interpreting data by observing what people do and say.

Five Big Words - Social Research Methods

A little knowledge about methodology will provide us with a place to hang our statistics.Research Methodology Series Mediator and Moderator Variables in Social Science Research.I will strengthen your understanding by providing examples of phenomena and their corresponding variables below.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).SimplyEducate.me is accelerated by CDN77, a content delivery network.My topic is: Attitude towards infertility screening among males.

It might be that repeated exposure to pollutants as opposed to age has caused the difference in lung capacity.Pingback: Market Analysis: The Pizza Study - SimplyEducate.Me.From these observations it may be possible to construct generalizations.

When the study includes naturally formed groups, the variable under study is a subject variable.If our strata were religious affiliation, stratified sampling would ensure sampling from every religious block or grouping.

The design of a clinical trial is very similar to that of a true experiment.Correlational research can be accomplished by a variety of techniques which include the collection of empirical data.Measures that were taken included heart rates before and after blood tests, ease of fluid intake, and self-report anxiety measures.Thank you so much for explaining it in a way that a slow witted like me can comprehend.Once again, there are two groups: a treatment group (the group that receives the therapeutic agent) and a control group (the group that receives the placebo).
