What is a dependent variable? Provide at least two examples.
A dependent variable is a variable that is being measured or observed in an experiment. It is the variable that is affected or influenced by the independent variable. It is called "dependent" because its value depends on the changes made to the independent variable.
Examples of dependent variables:
1. Test scores: In an educational study, the dependent variable could be the scores obtained by students on a test. The independent variable, in this case, could be the teaching method or the amount of time given for preparation. The test scores would be dependent on the changes made to the independent variable.
2. Reaction time: In a psychology experiment, the dependent variable could be the reaction time of participants. The independent variable could be the different stimuli presented to participants. The reaction time would be dependent on how participants respond to the changing stimuli.
