score world versus slope.

• Types of studies– Census, sample survey, experiment, observational

• Survey Types– Population, samples, SRS, stratified, cluster,

systematic– Bias: voluntary, convenience, undercoverage,

nonresponse, response

units, bias, confounding vs. lurking, placebo, blinding, blocking, matched pairs, causation

Test Tips • Multiple Choice

– Underline key words in the question– Eliminate answers– Draw Pictures– Guess only if you can eliminate some choices

• Free Response– Answer the question as asked in context (underline)– Don’t Panic ~ 1 question won’t kill you.– Answer the easier questions first– Leave enough time for the IT!– Draw Pictures– Use statistical language correctly– Decimal Places (2 for z-score, 4 for p-value)
