04/28/04 - identify sample and population, why and when we use samples; - read graphs. whithout looking at actual data answer questions about center and variability of the data. know which measures are better; - discrete random variable - probability calculations; - cont random variable - Normal - probability calculations using z-table; - what sampling distribution is and why we need to know it; - Central Limit Theorem - why is it important? - confidence intervals - how to interpret? - hypothesis testing - how to state Ho and Ha, how to draw conclusion, Type1 and Type 2 errors; - "Situation questions" - what test procedure can we use (1 sample z- and t-tests, 2-sample tests (independent vs paired), ANOVA, Chi-Sq, Linear Regression); be sure to check the needed conditions; -CI vs Hypothesis Tests. |
