Document Summary
Psych: repeated measures anova, one independent variable. Responses within same subject will be compared. Also known as within subjects anova: participants experience all conditions, methodological concerns. Conditions may differ in more ways than intended. Demand characteristics due to repeated measurement of same dv: statistical benefits (if avoid above problems) Due to individual differences transient states etc. More likely to detect effects of iv. Could look at variability within subjects instead of groups: scores should be different across groups (part of manipulation, e(cid:448)e(cid:374) if there is (cid:374)o effe(cid:272)t of a, (cid:448)aria(cid:271)ility (cid:449)ithi(cid:374) ea(cid:272)h su(cid:271)je(cid:272)t s respo(cid:374)se is likely (cid:271)e(cid:272)ause of error. A subjects personality, mood, etc. may cause them to respond differently from one condition to the next. Even in the absence of an effect. Even if there is no manipulation, participants may just respond differently.
