Question 1023049: A set of data has a mean of 0.5 and a standard deviation of 0.01. A data point of the set has a z-score of 2.5. What does a z-score of 2.5 mean? Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! It means the original sample score from which it came is at a distance of 2.5 standard deviations from the original mean of 0.5. (The original x-score is 0.525 by a direct application of the formula .)
