The variable that the experimenter wants to prevent variation in is the independent variable. This is the variable that is intentionally changed or manipulated by the experimenter to see its effect on the dependent variable. By controlling the independent variable and keeping it constant, the experimenter can ensure that any changes in the dependent variable are a result of the manipulation of the independent variable.
"dependent variable" comprises TWO words. Which word do you want in the sentence?
When someone wants the results of an experiment to come out a certain way, it is called experimenter bias or confirmation bias. This can lead to skewed results and undermine the validity of the experiment.
To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
Because you want to see how the experimental results change due to only that one variable change. If you used two variables, and the results varied, how would you know which variable contributed more to the change if at all? It can be done this way, but one variable at a time will allow you to make sense of your data much more efficiently.
You want lots of friction to prevent slipping when walking on icy surfaces, to slow down a moving object like a car or bicycle, or to grip a pen or pencil when writing.

The independent variable
In any experiment there are many kinds of variables that will effect the experiment. The independent variable is the manipulation for the experiment and the dependent variable is the measure you take from that experiment. Confounding variables are things in which have an effect on the dependent variable, but were taken into account in the experimental design. For example, you want to know if Drug X has an effect on causing sleep. The experimenter must take care to design the experiment so that he can be very sure that the subjects in the study fell asleep because of the influence of his Drug X, and that the sleepiness was not caused by other factors. Those other factors would be confounding variables.

independent
An Independent variable is what you control; you decide the focus of your experiment and what you control on the independent variable. Dependent variable is what you want to look at or find results for; you decide what you want to see from manipulating your independent variable.
You can use any variable that you want.
It depends on what you are looking at. If you want to look at changes in variable Y when a variable X is changed, then X is the independent variable and Y is the dependent. But if you want to look at changes in X which accompany changes in Y, then Y is the independent variable and X is the dependent.
I suppose you want to ask about variable initialization.Java initialize its variables in its constructor.
A dependent variable is a variable dependent on the independent variable. A control variable is something you want to try to keep the same. A dependent variable is something you measure. An independent variable is something you change.
It depends on what you want to convert it to.
