1 Producing good data through sampling and experimentation
question to be answered - what variables will be measured? organize! types of variables measured: categorical & continuous simple random sampling (SRS) completely randomized experimental design matched pairs Descriptive analysis graphical and numerical methods for single variables (univariate analysis) - shape, center, spread graphical and numerical methods for bivariate relationships: categorical vs. categorical; categorical vs. continuous; continuous vs. continuous

2 Transition to inferential statistics through probability
general introduction to probability including simple and, or, and not rules; relative frequency interpretation sampling distributions for counts & proportions and for means important distributions include: uniform, binomial, normal, t, and chi-square Inferential statistics include confidence interval estimation and hypothesis testing. Confidence intervals for p; for m ; for md ; for m1 - m2 ;

3 Review old tests and quizzes
Hypothesis testing for m ; for md ; for m1 - m2 for association Don't forget your "formula sheet" for the exam - must be turned in with the exam. Do as many of the assigned homework problems you can do before the exam… Review old tests and quizzes Online, look at the videos and do the chapter quizzes Read the book & look for the "boxes" and review the chapter summaries
