Document Summary

Psyc 300b - chapter 7: analysis of variance (anova: factor: the independent variable (iv) of the study. The different levels of a factor are the operational de nitions of the iv: multi-groups design: research design for k > 2, which consists of more than 2 separate, completely independent groups/samples/conditions. Different types of multi-group design include: (a) single factor (1-way) design 1 independent variable with several levels/conditions/groups: 2 types of single factor designs: (1) 1-way between groups/independent groups separate groups of participants for each level. Probe with planned & post-hoc tests, & apply f-statistic: mathematically, t2 = f. Random or unexplained error (iv) randomization test (random assignment model) For each condition, there are the 3 distributions population, sample, & sampling distribution. You must combine (pool) the various sampling distributions into 1 sampling distribution of the f statistic (ex. thus for k = 3 (1 iv with 3 levels) there are 10 distributions)
