Wilcoxon Test on Jamovi + Example Results Section

[@sitech-x3r]

hello, I would like to ask if the wilcoxon test can be used to test a one-tailed hypothesis i.e. for the example, the null hypothesis will be not be accepted and therefore the treatment was able to improve stress levels? thank you for the concise tutorial!

Hi, thanks for your question. I don't think there's a way of telling Jamovi that you have a one-tailed hypothesis. However, you can convert a two-tailed p value into a one-tailed p value by dividing it by 2.

@ thanks for the clarification! I’m assuming the p-value calculated by jamovi is already the two-tailed one?

@@sitech-x3r Yes, that's right.
