Standard error of the mean (SEM) and asterisks in t-test graphs
Hello everyone,
I am a biologist and I usually use Prism for my statistics. Although it is extremely useful and easy to use, it is becoming too expensive for many researchers. I am looking for a credible, open-source alternative to Prism for this type of analysis.
JASP seems powerful for this purpose. In fact, I am starting with the simple and basic Student's t-test to see if it can meet our needs.
-Is there a way to plot SEMs on the bars?
-Also, could JASP graphically represent the “asterisks” between the different conditions?
Thank you for your help. I sincerely hope that JASP can be a real alternative to Prism.
Best

Hello Cedric,
Interesting. I think we had much of what Prism has to offer already, and whatever is missing we can easily add. The problem is that we have such a long to-do list. Anyway, about the t-test: (1) yes, we can show the SEMs on the bars (in both directions, of course -- really, one should not use bars at all but points instead, but OK). (2) about the asterisks -- I have had this request before. I will ask what the status of these requests is. Below a screenshot of the t-test GUI with a small subset of options ticked:
