Examples Of Independent And Dependant Variables. As the experimenter changes the independent variable the effect on the dependent variable is observed and recorded. The dependent variable is dependent on the independent variable. Here your controlled variable would be the amount of light and water received by the plant. Here are several examples of independent and dependent variables in experiments.
The dependent variable is the impact the drug has on cancer. You want to compare brands of paper towels to see which holds the most liquid. If you do not control these factors your dependent factor. As the experimenter changes the independent variable the effect on the dependent variable is observed and recorded. In most studies independent variables represent the quantity the researchers are going to manipulate. In an experiment the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
A scientist studies the impact of a drug on cancer.
The independent variables are the administration of the drug - the dosage and the timing. An example of a dependent variable is depression symptoms which depends on the independent variable type of therapy. In this example the amount of water given to the plant is controlled by the researcher and thus is the independent variable. In this sense some common independent variables are time space density mass fluid flow rate and previous values of some observed value of interest eg. Human population size to predict future values the dependent variable. In this example the scores on the math exams are the dependent variable and the classical music is the independent variable.
