HypothesisUsed with I.Q. and E.G.If the independent variable does this,then the dependent variable will do that.

EngineeringgoalStating why you built something.

InvestigativequestionAsking about the relationship between variables:What is the relationship between the independent variable and dependent variable?

Method3
