One point of clarification. I might suggest replacing the word "accuracy" with "precision or consistency." Accuracy implies both (a) validity, and (b) correspondence to an objective level (as in this clock is accurate because it is calibrated to a universal clock setting). Since reliability reflects consistency of a true score but not necessarily the meaning of such scores, it might be misleading to label SEM as capturing accuracy.

I wish that I had found your channel earlier. Please make more of these presentations!
Thank you for making this video! It made everything clear to me :)
If I have a data set where the reliability isnt provided (which it rarely is) I cant calc SEM?
I'm afraid not.
How on gods green earth is R calculated?

hi there. i need to know how you calculate SD when two raters(A&B) scores are present.
