Independent and Dependent Variables
Transcript of Independent and Dependent Variables
Dependent Variable Independent Variable A variable that stands alone.
Variable that influences the outcome.
You can not change!!!! Dependent
Outcome is assumed to depend on other factors.
Can Change! Example of IV Someone's age
How much you go to school, what you eat, or how much T.V. you watch CAN NOT change your age. Examples of DV Test Scores
How much you studied, how much you sleep, how hungry you are CAN change your test score. (Independent variable) causes a change in (dependent variable) and it isn't possible that (dependent variable) could cause a change in (independent variable). Example #1 A scientist studies the impact of withholding affection on rats. Example #2 A scientist studies how many days people can eat soup until they get sick. Example #3 A teacher studies student's behaviors after 3 weeks of indoor recess. Example #4 The number of cigarettes a person smokes increases his or her chance of getting cancer.
