Document Summary
Assess reliability of ndings through intra-subject replications: replicate the same treatment within the same individual (abab) Assess generality of ndings through inter-subject replications: repeat the same treatment among different participants. Must ensure to vary only 1 thing at a time in order to evaluate effects. Minimizes the change of type i error: emphasizes publishing statistically signi cant ndings, clinical signi cance: the practical importance of a result. Want to research powerful variables that produce large effects, rather than variables that produce small effects: power: the probability that a statistical test will nd a signi cant difference when a difference actually does exist in the population. Rather than focusing on increasing sample size, the researcher can focus on increasing effect size. Dv coincide with manipulation does not require the reversal of the behaviour involves manipulating 1 of the behaviours/subjects/settings & using the others as the baseline comparison.
