What is a dependent variable in research
What is an example of independent variable in research?
The following are illustrative examples of independent variables. Changing the amount of fertilizer given to plants as an independent variable. In this experiment, dependent variables might be plant height and weight. Control variables might include water, sunlight and soil. Giving medication to one group and a placebo to another.
What best describes the dependent variable in an experiment?
The dependent variable is the variable that is being measured or tested 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.
How do I find the independent variable?
The independent variable is always displayed on the x-axis of a graph, while the dependent variable appears on the y-axis. Time is a common independent variable, as it will not be affeced by any dependent environemental inputs.
How do you determine independent and dependent variables?
How do you determine independent and dependent variables? You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis).

In a qualitative study, inquirers state research questions, not objectives (i.e., specific goals for the research) or hypotheses (i.e., predictions that involve variables and statistical tests). These research questions assume two forms: a central question and associated subquestions.

dependent variable is a measure of the behavior of the participant that reflects the effects of the independent variable. The dependent variable is the CONSEQUENCE. A specified variable is not ALWAYS an independent or dependent variable.

and treatment response is the dependent variable. It should be obvious, now, that a hypothesis can also be defined as the statement of an expected relationship between an indepen-dent and a dependent variable. Or, expressed visually, (independent variable) (arrow) (dependent variable) = hypothesis. It would be a waste of time and energy to

• A. Variable functions related to presumed causality include independent and dependent. • Dependent variable: A phenomenon that is presumed to be affected by another phenomenon (Williams, 1986) that may be measured or manipulated (depending on the type of research design). • Response variable or output.
