Regents Review Some Suggestions Read the question twice

Regents Review

Some Suggestions • • • Read the question twice. This is NOT a race. Read the info regarding the question. LOOK at everything in the diagrams. Do NOT easily (quickly) make assumptions. Think of your answer before you read the choices • Read ALL the choices. Read each choice to the end of the sentence. Be aware of the possibility of trickery!

Scientific Method • • Hypothesis Inference observation Conclusion Independent variable Dependent variable Control Large sample size
