Sequential hypothesis testing with Bayes factors: Efficiently testing mean differences.

Abstract: Unplanned optional stopping rules have been criticized for inflating Type I error rates under the null hypothesis significance testing (NHST) paradigm. Despite these criticisms this research practice is not uncommon, probably as it appeals to researcher's intuition to collect more data in order to push an indecisive result into a decisive region. In this contribution we investigate the properties of a procedure for Bayesian hypothesis testing that allows optional stopping with unlimited multiple testing, even … Show more

“…A BF represents the ratio of the probability of the data given a null model to the probability of the data given an alternative model and thereby offers a gradual quantification of evidence (Schönbrodt, Wagenmakers, Zehetleitner, & Perugini, 2015). A BF10 of 3, for example, states that the data is 3 times more likely in the alternative model than in the null model.…”

“…Third, Bayes factors allow one to accumulate data until enough evidence has been acquired for one of the competing hypotheses, compared to the other one (Cornfield, 1966; Deng, Lu, & Chen, 2016; Schönbrodt, Wagenmakers, Zehetleitner, & Perugini, in press). Indeed, in Bayesian analysis, more evidence usually increases support for one of the competing hypotheses, and not necessarily to a change in the direction of the results (see Schönbrodt et al, in press).…”
