Identify dependent and independent variables and apply them to contexts. Independent and dependent variable examples in a study to determine whether how long a student sleeps affects test scores, the independent variable is length of time spent sleeping while the dependent variable is the test score you want to compare brands of paper towels, to see which holds the most liquid.

You may find it difficult to understand just what variables are in the context of research especially those that deal with quantitative data analysis this initial difficulty about variables becomes much more confusing when you encounter the phrases “dependent variable” and “independent variable” as you go. You can look at correlations across variables regardless of whether they are dependent/independent in a strictly exploratory study, you might do summary exploration, means, medians, standard deviations and graphing of multiple variables in this peter flom, author or co-author of dozens of papers. Hypotheses rather than the finding of answers, research is primarily focused on the asking of questions when writing a research paper, the research question or hypothesis is the spine upon which everything (the second category of the independent variable) with respect to c (the dependent variable) rq1 below is. Define the variables there should be three categories of variables in every experiment: dependent, independent, and controlled dependent -- is what will be measured it's what the investigator thinks will be affected during the experiment for example, the investigator may want to study coffee bean growth possible.

Generally speaking, in any given model or equation, there are two types of variables: independent variables - the values that can be changed or controlled in a given model or equation they provide the input which is modified by the model to change the output dependent variables - the values that result from the.
From your research question after identifying the dependent variable, you then determine, on a theoretical basis (see below), which factors influence the phenomenon in question and which you will therefore use to explain it depending on the scope of your research paper, you may choose to identify one, two or three. I research question(s) / purpose of the article ii hypothesis iii variables a independent variable b dependent variable iv methodology a who participated b what did they do v major findings. The foundations of quantitative research are variables and there are three main types: dependent, independent and controlled the researcher will manipulate an independent variable in an effort to understand its effect on the dependent or controlled variable in other cases when manipulation is not an.

The dependent variable is the variable that is being measured in an experiment for example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured in a psychology experiment, researchers are looking at. This article begins by defining the term variable and the terms independent variable and dependent variable, providing examples of each it then proceeds to describe in addition, the article links terminology about variables with the concept of levels of measurement in research keywords: confounds. The independent variable affects or determines the values of dependent variable the dependent variable is sometimes referred to as the outcome variable because the resulting outcome of manipulating the independent variable is typically the focus of the research study the dependent variable is the one that the. Even if you are primarily interested in the relationship between an independent variable and one primary dependent variable, there are usually several more for this reason, the researcher might have participants complete the paper-and- pencil perceived stress scale and measure their levels of the stress hormone.
