      The independent variable is typically the variable being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. For example concerning nutrition, the independent variable of your daily vitamin C intake (how much should I take) can

      An independent variable is a factor that is manipulated in an experiment. The scientist decides whether or not subjects are exposed to the independent variable. The dependent variable is measured to determine if the changing of the independent variable had any effect. For example, to test a hypothesis that eating carrots improves vision, the

Variables that cause something to change are called independent variables or manipulated variables.

      The independent variable is the part of the experiment that you change. The dependent variable is what you’re measuring a change in. The dependent variable changes depending on the independent variable. Example: You’re testing different fertilizers and their effect on the height of grass. The type of fertilizer is the independent variable.

      The independent variable is the one that is changed/controlled by the scientist. To ensure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens or results from that change.

      Independent variable: The independent variable is the single condition (variable) that is manipulated to see what impact it has on the dependent variable. The independent variable is the factor that causes the dependent variable to change. E.g. the temperatures the trees are exposed to is the independent variable in the vine maple example.

      What is a variable? A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types of variables- independent and dependent. Independent variable: is a variable that stands alone and isn't changed by the other variables you are trying to measure. Dependent variable: is

      The independent variable is the one that is changed by the scientist. In an experiment there is only one independent variable. As the scientist changes the independent variable, he or she observes what happens. The dependent variable changes in response to the change the scientist makes to the independent variable.
