It depends upon what you are studying. If you are studying the effects of change in water temperature on health of fish, then it is the independent variable. If you are studying the impact of putting the aquarium near a window on a sunny day then it is the dependent variable.
Independent Variable is what you are CHANGING and Dependent Variable is what you are MEASURING ! get at me on aim if i helped Gurlsofly5
The independant is the thing you are changing and the dependant is the measure
You can tell which is the independent variable and which is the dependent variable by changing the equation into an "if/then" statement. Example: y = 3x In this example, x is the independent variable and y is the dependent variable. If you give me x, I will tell you y. If x = 1, then y = 3 If x = 2, then y = 6 So you give me the independent variable, and then I will be able to determine the dependent variable.
An independent variable in science is the part of an experiment that you are purposely changing. For example, if you were to do an experiment on what type of water is best for plants, then the "special water", which might be salt water is the independent variable.
The truth is that you can't actually answer, given the information you have. But that's not the answer you are looking for! So, the equation you have is y = 6x+8. There are two variables here, x and y. If you know what x is, you can calculate y as follows: you multiply x by 6 then add 8. So if x is 2, then 6 lots of x is 12, and adding 8 we get 20. So y is 20. The general expression y = mx + c describes a linear relationship between two variables - m is referred to as the gradient and c is called the intercept. This is because if each of the pairs of x and y (e.g. x=2 and y=20 above), the line which join them intercepts (crosses) the y axis at 'c' and has a gradient (steepness) of 'm' (i.e. as you move one unit along the x axis, you go 'm' units up the y axis). So which is dependent and which is independent? Earlier, we calculated y from x. This is the easiest thing to do with this equation. We can say that 'y is dependent on x' or 'x is the independent variable'. Mathematically speaking, though, we could just rearrange the equation (you can see that x = (y-8)/6 by taking 8 away from both sides and dividing both sides by 6). Then it looks like we've switched which one is dependent and independent. But we haven't really - and that is because you are not really asking a maths question, to do with equations, but a science question, to do with causes and effects. In science, we often choose what x's we will use and measure the y's. *This* makes y dependent, but only if we choose it properly - it should actually change as a result of changing the x. So y could be 'reading age' and x could be 'actual age in years'. Most people's reading age increases as they get older (at least up to a certain age). But it is how old they are that is causing their reading age to increase. So we would say that 'actual age in years' is the independent variable and 'reading age' is the dependent variable (because it depends on their actual age). And so if we were doing an investigation into this relationship, it would be conventional to call the 'actual age in years' x and the 'reading age' y. It is normal to call the independent variable 'x' and the dependent variable 'y'. I think that's what you really want to know, but it is important to know why.
Independent and dependent variables are the variables that change during the course of an experiment. An example might be an experiment on how temperature affects plant growth. Changing the temperature is the independent variable, while the level of plant growth that results is the dependent variable.
Independent is the thing that you are changing which is probably the food and the dependent is the thing is changing . I think. .....

Dependent Variable the independent variable is the one you change to get the dependent variable. The control group is the thing that you leave the same throughout your experiment. Hint: You don't want too many independent variables, it will mess up the experiment.
The independant is the thing you are changing and the dependant is the measure
The independent variable in an controlled experiment is what you are changing
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
The independent variable is the variable which you change. It is not changed by any outside factors and so is independent of them.The dependent variable is the variable which is changed by the independent variable changing and which you measure. It is dependent on another variable.
The independent variable in an controlled experiment is what you are changing (for example, amount of water or sunlight a plant gets). The dependent variable changes because of the independent variable. Its the outcome of the independent variable.
In the color changing milk experiment, the dependent variable is the color of the milk (whether it changes or remains the same), which is affected by the independent variable, such as the addition of dish soap or food coloring.
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
That process is known as measuring the dependent variable. The dependent variable is the outcome or response that is measured to assess the effect of changing the independent variable in an experiment or study.
