Bayesian one-sided independent samples t-test: question about the sequential analysis plot
I am running a Bayesian independent samples t-test where I have specified that my hypothesis is that Group 2 has scored higher than Group 1. The sequential analysis plot looks as attached. Initially I thought the reason why the first ten participants do not move the evidence in either direction is because they are in Group 1, but Person 10 is in Group 2. Does this mean that the first 10 participants do not contribute to the evidence and only the information of the second group contributes? Is that a good thing or does this imply something may be wrong with my sample?
