PSYC 3000 Study Guide - Quiz Guide: Standard Score, Standard Deviation, Statistical Parameter
Document Summary
With hypothesis testing: we can answer questions about our model. Alternative: the equation; if we reject the null. > < or does not equal (two tailed) Before doing tests: we check independence condition, random condition, success/failure condition. Once we solve: we then ask how likely the data we observed would be were the null hypothesis a true model of the world. P high: fail to reject/accept null hypothesis. P low: reject; what we have observed is unlikely if our null was true. Or is it two tailed: increase/decrease/has it changed: model; are the conditions satisfied (page 379. independence, random, success/failure: p(n) q(n) > 10 each, mechanics, conclusion. Sometimes we follow up with confidence interval: (page 383) We can not find the standard deviation from the null proportion (* if we rejected it, we can not use) Example from class: descriptive, analyze, bring to dv. Made 99 percent confident interval; 99 percent confident between 17 and.
