I am having difficulty with statistics..I am taking stats 4, but haven't taken 3 yet.
Explain deviation below or above the means please.
ex. If bill received a NCE score deviation below the mean, what would his score be? which is 10. Can you explain the standard deviation above the means?

It is always best to take the courses in order. Each one builds on the knowledge of the preceding course.
If it is a standard deviation below the mean, That means it is at about the 16th percentile. Z score is the score in terms of standard deviations.
1 = Z = (scoremean)/SD
You do not indicate the mean or SD.
