how many standard deviations beyond the mean each observation is. Pam's score is (1800 - 1500) / 300 = 1 standard deviation above the mean. Jim's score is (24 - 21) / 5 = 0.6 standard deviations above the mean. Standardizing with Z scores. These are called standardized scores, or …

www.wrightslaw.comThe bell curve is measured in units called Standard Deviations (SD). Standard Deviations describe how far test scores spread out or deviate from the Mean. The center of the bell curve (the Mean) is at 0 (zero) Standard Deviations. A score that is zero Standard Deviations from the Mean is always at the 50th percentile (PR = 50). On the bell ...

The subscript usually indicates the quantity that the standard deviation is calculated for, e.g., s v stands for the standard deviation of velocity measurements, whereas s a is the standard deviation for acceleration data.
