Can someone please explain what it means to have a SEM=3?
If the standard error of measure (SEM) ranges from 1.5 to 4.74 with the majority smaller than 3.0. What does it mean if a child had a score of 70, with SEM=3?

This kind of feels like a homework question.
Any how… there’s a 68% chance that the true score the child would have on the test is between 67 and 73.
I think you need to check your textbook. Standard error, in general, is a description of the accuracy of statistics. What it means in your specific case is impossible to tell. The child had a score of 70, fine. But was that out of 1000? 100? 75?
A numerical score is meaningless unless you have the context of what the limits are and what was being measured.
It’s not a question for homework. I am reading about the Developmental Assessment of young children. I have to read it and we are just going to discuss it in class. The study says the reliability coefficient ranges from .90 to .99 ( which I know is incredibly good) . Then it says SEM( standard error of measure) ranges from 1.5 to 4.74 with the majority smaller then 3.0. In the study it talks about a child who had a score of 70 with then SEM=3 . I just wanted to know what that means. @elbanditoroso @Lightlyseared
I hope this link might help.
