I wanna ask you about Reliability function In JASP
Hello. I know i'm asking a lot of question, but i need more help for my homework.
I found there are 'average item correlation' function, but are there any way I can see the range of item correlation?
and, is 'item-rest correlation' is same word for item-total correlation(CITC)? My homework calls for CITC.
Thank you so much for your help.

No worries. I'll ask our experts.

Hi,
unfortunately within the reliability module there is no way to get a range of inter item correlations. Within the regression module, however, you can get a correlation table for all items. With more than a few items extracting the range might become a bit tedious though.
Item rest correlation is not the same as item total correlation. It seems redundant to compute the correlation between an item and a total test score that contains the item itself. So, unfortunately, there is no way in JASP to get the item total correlation right now.
I hope this answers your question, and also the one you posted here (https://forum.cogsci.nl/discussion/6802/variables-dont-go-to-the-right-pane#latest)?
Best,
Julius
