W., Freund, R.J.– Recommended SAS for Linear Models, 4th ed., SAS Institute Inc, Cary, North Carolina, 2002, ISBN 1-59047-023-0 Marasinghe, M.G. and Kennedy, W.J. – Recommended Data Analysis Using SAS, Springer, 2008. ISBN 978-0-387-77371-1 3 Outline • Comparative studies (two populations or treatments) – Random samples – Role of Randomization • Analysis of variance ( more than two populations ) • Blocking/matching to reduce variance • Comparing proportions • Simple linear regression • Multiple regression • Analysis of covariance • Generalized linear models • Factorial experiments • Nested designs/random effects 4 Useful Concepts • Calculus and matrix algebra • Statistics Concepts: – Random variables – Probability distributions (binomial, Poisson, normal) – Simple random sample – Summary Statistics (shape, center, spread) – Data displays (histogram, stem/leaf, boxplot, scatterplot) – Estimation (sample mean, sample median, sample proportion, sample variance, standard deviation) – Correlation and association – Statistical Inference (tests of hypotheses, confidence intervals) 5 Computational Resources • Simple calculator • SAS statistical package – Buy it from ITS for $6/yr. (Go to http://www.it.iastate.edu/sldb/ and click on SAS for Windows under Statistical Software) – Run it on the Statistics Department Terminal Servers (available to all ISU students).
