It's good to if you can- for example, I can set a machine to insert a certain amount of something into my experiment, but if I can measure how much it actually put in, I will be more confident in my data. In some situations, it's not possible (particularly quantum physics, where observing something can change it).
The independent variable is the one that you change in an experiment. The dependent variable changes because of the independent variable. You control the independent and observe the dependent.
In an experiment, the independent variable is the variable that is manipulated by the experimenter in order to observe and measure how it affects the dependent variable. For example, an experiment in which the experimenter wants to observe and measure the effect of force on the acceleration of an object, force would be the independent variable and acceleration would be the dependent variable. The experimenter would apply different amounts of force to an object, and then observe and record the object's acceleration with each amount of force. On a graph, the independent variable would be on the x-axis, and the dependent variable would be on the y-axis.
Yes, independant variables are the variables that are changed in an experiment to observe the results, called the dependant variable.
The independent variable.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.

Independent variable is the one to be investigated; the one that will be changed to get results. If you are still finding it too hard just keep this in your mind-- Independent variables answer the question "What do I change?" in an experiment. Dependent variables answer the question "What do I observe?"!
dependent: factors of a experiment that scientist observe, and can be changed by the outcome of the independent variable independent: a factor of a experiment that changes because you change it on purpose
The three kinds of variables are independent, dependent, and controlled. An independent variable is either changed or manipulated in order to observe its effect on the other parts of an experiment.
When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.
The independent variable.
Independent, it is in the name, more variables are: dependant variable- the one you keep the same control variable- mearsuring variable
Changes in the independent variable are independent of changes in any other variable,
