Independent or Dependent?
By Justin Fang
1.If a scientist conducts an experiment to test the theory that a vitamin could extend a person’s life-expectancy, then:
The independent variable is the amount of vitamin that is given to the subjects within the experiment.
The dependent variable is life span.
2. John is saving money for a vacation to Canada. The more money he saves for the trip, the more days he will be able to stay in Thailand.
Independent the amount of money he saves
Dependent the amount of days she stays
3. John is making frosting for some cupcakes he baked earlier. The number of cupcakes he made dictates how much frosting is needed.
The independent variable is the number of cupcakes
The dependent is the frosting needed.
