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).

Independent variable is known as?
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.
What is an independent verible?
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.
Can you change an independent variable?
Yes, independant variables are the variables that are changed in an experiment to observe the results, called the dependant variable.
What is the manipulating variable the dependent variable or the independent variable?
The independent variable.
What is the diffrence between dependent variable and 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.
