Probably dumb question about Bayesian t tests in JASP
This is probably a really dumb question, but when I run a Bayesian t test on some data using the default scaled Cauchy prior (sigma=0.707) I get one BF, yet when I define a custom prior to be a Cauchy with the SAME scale, I get a different BF. Note that my data set is huge (~20,000 points). My first thought was that the scale in the default prior is really an irrational number and 0.707 is rounded simply for display purposes. Is this true?
