Score is an old term meaning 20. Similarly, we still use dozen to mean 12 of anything. The most famouse example I know is when Abe Lincoln used "Four score and seven years ago" in a speech. It was a fancy way of saying 87 years. So 7 score of whatever you are counting would be 7x20=140 of them.
87
87. A score is 20.
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
Yes. If a score is below the mean, the z score will be negative.
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.

score like 4 score and 7 years ago our fathers... score like 4 score and 7 years ago our fathers...
Yes.z = (raw score - mean)/standard error.Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.
my meld score is 16. what does that mean?
it means that the score is above the mean
If by USC you mean South Carolina Gamecocks, the score was USC 29 - Clemson 7
A score is 20 years so four score means 80 and add 7 years to that?
Yes. If a score is below the mean, the z score will be negative.
If you really want to evaluate the 7-year-old and help him if he needs it, please get off of the internet and take him to see somebody who can talk to him, somebody who you can be sure knows what the tests mean, and somebody who you can be sure knows what they're talking about.
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
