Bayesian one sample t-test versus Wilcoxon signed-rank: completely different result in JASP?
I want to compare my data sample to an established value and I've been using a Bayesian one sample t-test in JASP 0.13.1 to do so. However, one of my data samples violates the normality assumption so I switched to the Wilcoxon signed-rank within the same feature in JASP. I noticed that the results are completely different! E.g., one sample has a mean of 63.9 (SE 1.6) and the t-test gives me a BF+0 of 2.9e+6 when comparing this with 50, strongly indicating that my sample deviates from 50. However, switching to the Wilcoxon with the same sample results in a BF+0 of 0.270 indicating no difference from 50 which seems very strange to me.
Could this be a bug? Doing the non Bayesian Wilcoxon also gives me a highly significant difference from 50.
