An example of a dependent variable is depression symptoms which depends on the independent variable type of therapy. In an experiment a researcher wants to understand how changes in an independent variable affect a dependent variable. If some of them are slightly skewed keep them as they are.

We can conclude that the predictable variable measures the effect of the independent variable on the test units. For example if we want to explore whether high concentrations of vehicle exhaust impact incidence of asthma in children vehicle exhaust is the independent variable while asthma is the dependent variable. These variables can be any alphabets from a to z.

This article begins by defining the term variable and the terms independent variable and dependent variable providing examples of each. Dependent variable - the variable that the researcher is testing and measuring in relation to the independent variable for example how much weight the research group actually loses The researcher determines whether manipulating the independent variable leads to different outcomes regarding the dependent variable.

In research variables are any characteristics that can take on different values such as height age temperature or test scores.
