There math tools used in a experiment (Ex: Like in a hypothesis) If u use them u will be able to measure your results and have accurate data.
Independent variables answer the question "What do I change?" Dependent variables answer the question "What do I observe?" Controlled variables answer the question "What do I keep the same?"
Math: Independent variable is what you change. Dependent variable is what you measure.
dependent variable is the thing you measure in an experiment and a independent is the one you change.
The Independent Variable, in an experiment, is the variable that is being manipulated and the Dependent Variable is what will be affected.
