2) Formulating an explanation
3) Carrying out research designed to support of refute the explanation 4) Communicating the findings
Hypothesis – a prediction, stemming from a theory,
stated in a way that allows it to be testedoperational definition * Cannot say 1 thing causes another until it is put through an experiment

Experimental method:
Independent variable – the variable that is manipulated by an experiment Dependent variable – the variable that is measured and is expected to change as a result of changes caused by the experimenter’s manipulation of the independent variable Significant outcome – meaningful results that make it possible for researchers to feel confident that they have confirmed their hypotheses
