= Square Root of (Score - Mean) Squared |
Homework Answers
Z score standardized with respect to location and scale. Hence we need to subtract the mean from original score and divide with standard deviation.
Therefore the formula of z score is =
(Score - Mean) / Standard Deviation

In a normal distribution, the mean corresponds to: Standard Score: z = Percentile: Which of the following statements are TRUE about the normal distribution? Check all that apply. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean. The mean corresponds to the z-score of 1. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. A z-score is the number of standard deviations a...
