      Dependent & independent variables | Algebra (video) | Khan Academy (4)

      The dependent variable is supposed to DEPEND on the independent variable.
      If I do make a plot to show how much water I drink depending on what the temperature is outside. The # of cups of water is the dependent variable. This leaves the independent variable to be the temperature!

      You can also tell if it's the other way around. Does the temperature outside depend on how much water you drink? No, no it doesn't! Tip for the future, if it does seem to make sense both ways then you might have a junk design for your experiment.

      Assuming you're asking about independent and dependent variables. The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes because of this control. For instance, if you were to be measuring the number of miles you drove in any number of hours at a constant speed, the controlled independent variable is the time in hours and the dependent variable is the distance you drove in miles.

    How come the world uses Dependent and independent varible not only in math but in science to? Do they mean the same thing or what?

      You're right! In both math and science, we need a word to describe a variable that changes as something else changes (dependent ) and a variable that does not change as a result of something else changing, and instead causes something else to change (independent).

      The dependent variable is the one that depends on the value of some other number.
      If, say, y = x+3, then the value y can have depends on what the value of x is.
      Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.

      The independent variable is the variable that changes the dependent variable. So, say if you drink water from a large water bottle, the amount of liters you drink depends on how many times you drink from your water bottle. If you drink different amounts of water from the bottle, you will have a different amount of liters you drank

    For people who don't understand:

    The Independent variable = what varies in the Question/Example.

    The Dependent variable = The effect the Independent variable has.

    Hope this helped :]

      The dependent variable is usually graphed on the y-axis, and the independent variable is usually graphed on the x-axis. In addition, the value of the independent variable determines the value of the dependent variable and is used in experiments to test the value of the dependent variable.

      For example, if I were studying the influence of hours studied on the final grade received in a course, the number of hours (the input that changes the output) would be the independent variable and graphed on the x-axis, and the final grade received (the output of number of hours studied) would be the dependent variable and graphed on the y-axis.

    1. the amount of nitrogen in the soil
    2. the amount of phosphorus in the soil
    3. the amount of rainfall
    4. the amount of potassium in the ground

      You do not have a comparison of two things, which you need to have a independent/dependent relationship. Any of these could be compared over time.
      So if you have the amount of nitrogen in the soil over a given time period or rainfall per month over a year, or temperature from 4 am to 8 pm, these would all be the dependent variable with time as the independent variable.
