WebThe standard deviation of the z-scores is always 1. The graph of the z-score distribution always has the same shape as the original distribution of sample values. The sum of the squared z-scores is always equal to the number of z-score values. Z-scores above 0 represent sample values above the mean, while z-scores below 0 represent sample ... WebThe absolute deviation, variance and standard deviation are such measures. The absolute and mean absolute deviation show the amount of deviation (variation) that occurs around the mean score. To find the total variability in our group of data, we simply add up the deviation of each score from the mean. The average deviation of a score can then ...
