Validity, reliability and repeatability

Post by gvt »

I have two scales, one part A is the gold standard, and B is the model to test.
I take different records with different known weights and at different temperatures and on two different days.

What will be validity, reliability, and repeatability, and which statistical test can be done in Jamovi for each?

Hi. Judging from the details of your question, I don't think it's a simple matter of what test to do, or whether jamovi can do such a test. Rathe, your question pertains to the fundamental meanings and applications of the statistical terms, "reliability," "validity," and "repeatability."
