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. A score is 20.
The fx column in a Frequency Distribution Table is the frequency (f) multiplied by the Class Centre or score (x). If the score is 22. And the freqency for that score is 7. fx = 22*7 = 154 You can use the total of the fx column to find the mean. The total fx divided by the total frequency = Mean.
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.

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 equal to 20 units, so 5 scores would be 100 units in total.
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.
