The diamond ♦ is placed where we think your score lies. This diamond is placed on
your T-Score, which is a standardized score that is based on an average score of 50,
based on responses to the same questions in the United States general population.
The T-score also has a standard deviation of 10 points, so a score of 40 or 60
represents a score that is one standard deviation away from the average score of the
general US population.
The Standard Error (SE) is a statistical measure of variance and represents the
possible range of your score. The lines on either side of the diamond in your profile
report show the possible range of your actual score around this estimated score. It is
very likely that your score is in the range of these lines.
