From Reliability analysis, how should report SEM (standard error of measurement)? I understand that always with the "±" symbol before.
It is correct?

FYI, here's handy reference: https://www.researchgate.net/publicatio ... easurement

Would it be correct to calculate the SEM on the same scale for different weights? For example, compare all measurements between each other for 10kg, then all between each other for 20kg... and take the average SEM? Or should the SEM be reported separately for each weight?

If I want to calculate SEM only for 10kg measurements, how can I do it using Jamovi package SimplyAgree?
I have data of 10.1, 10.05, 10.2, 10.1, 10.05, 10.2, 10.1, 10.1, 10.02 and 10.01.
Is requirement to have 2 columns but I only want to calculate for data of 1 know weight, 10kg.
