whats the differance between variables dependent and independnt? {in science}?

Answer 1

Dependent vs. independent variables. Independent variables are those that are manipulated whereas dependent variables are only measured or registered. This distinction appears terminologically confusing to many because, as some students say, "all variables depend on something." However, once you get used to this distinction, it becomes indispensable. The terms dependent and independent variable apply mostly to experimental research where some variables are manipulated, and in this sense they are "independent" from the initial reaction patterns, features, intentions, etc. of the subjects. Some other variables are expected to be "dependent" on the manipulation or experimental conditions. That is to say, they depend on "what the subject will do" in response. Somewhat contrary to the nature of this distinction, these terms are also used in studies where we do not literally manipulate independent variables, but only assign subjects to "experimental groups" based on some pre-existing properties of the subjects. For example, if in an experiment, males are compared with females regarding their white cell count (WCC), Gender could be called the independent variable and WCC the dependent variable.

Answer 2

Say for example, you are doing a project on moods of different people. The dependent variable would be the people's moods because the temperature of the room can affect how they feel. The independent variable is when something that occurs does not depend on the rest of the situation. The independent mood in this project would be the temperature of the room because a person's mood cannot change the temperature but the temperature can change the mood.

Answer 3

The independent variable is the factor that you change to see what will happen.

The dependent variable is the difference that you count or measure = the results.

Example:

I think that pea plants will grow faster with more hours of light.

Independent variable: number of hours of light for my two groups of plants.

Dependent variable: height of plants.

You can remember that the independent variable comes first and it causes the differences in the dependent variable. Independent starts with I which is like a 1 (one) for first.
