Example Of Dependant Variable. If you determine the substance is necessary for proper nutrition a follow-up experiment might determine how much of the chemical is needed. 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. If you change the color of light independent variable then it affects plant growth dependent variable. In an experiment the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
In the previous examples gender was a qualitative variable that could affect the relationship between hours studied and resting heart rate while age was a quantitative variable that could potentially affect the relationship. Here are some other examples of dependent and independent variables in scientific experiments. 1 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. An example of a dependent variable is depression symptoms which depends on the independent variable type of therapy. If you change the color of light independent variable then it affects plant growth dependent variable. The dependent variable height depends on the independent variable age.
If plant growth rate changes then it affects the color of light.
Experiments to test improvements to products services or customer experience are often measured with customer satisfaction as the dependent variable. For example in an experiment about the effect of nutrients on crop growth. A scientist studies the impact of a drug on cancer. In this experiment dependent variables might be plant height and weight. If you change the color of light independent variable then it affects plant growth dependent variable. A Dependent variable is what happens as a result of the independent variable.
