If a researcher fails to control the relevant variables in an experiment, you could end up changing a bunch of different variables in an experiment, and you wouldn't be able to tell which variable is responsible for the results of the experiment.
You can have more than one variable, but it would take longer to solve.
The outcome of the experiment may not be linked to any one specific variable.
The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)
The factor in an experiment that responds to the manipulated variable
A manipulative or manipulated variable in an experiment is the variable that can be varied to give different results during the course of an experiment. For example to determine how much sugar will saturate a liter of water, we keep increasing the amount of sugar until the water becomes saturated. Here sugar is the manipulated variable. Very easy! At first, I was confused with it too!

A manipulated variable is the thing that can be changed in an experiment. example; your trying to see what paper towel would be more absorbant, your manipulated viariable would be either the type of paper towel you use or the liquid you use to test the absorbancy.
The variable deliberately changed in an experiment is called the independent variable. This variable is manipulated by the researcher to observe its effects on the dependent variable, which is the outcome or response being measured. By controlling and changing the independent variable, researchers can determine its influence on the dependent variable.
An experiment is almost always designed so that two (and no more) things will change.-- You, the experimenter, will change one of them as you desire.-- That will cause a change in the other one, which you will carefully measure.
No, a controlled experiment can have more than one variable. However, in a controlled experiment, only one variable is intentionally changed (independent variable) to observe its effect on another variable (dependent variable), while all other variables are kept constant (controlled variables) to ensure the validity of the results.
The factor in an experiment that responds to the manipulated variable
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.

An independant variable is the variable in science that you'll be changing throughout the experiment. Like if you were experimenting on plants, the independant variable is how many plants you'll be taking out and putting back in. For example, you take out one of the bad plants and include three more.
