Use this Z-Score Calculator to calculate the standard normal score (z-score) based on the raw score value, the population mean, and the standard deviation of Index of dbcolstatscores man page T-score scales the z-score to match a mean of 50 and a standard deviation of 10. This program allows generalized t-scores The IGF1 Z-Score Calculator can be used to calculate a patient's standard deviation score (as a Z-Score) based on IGF-1 patient results provided by Endocrine The SVI is a z-score deviation from the mean in units of the standard deviation, calculated from the NDVI or EVI values for each pixel location of a composite Z scores and Standard Deviations. Technically, a z-score is the number of standard deviations from the mean value of the reference population (a population whose known values have been recorded, like in these charts the CDC compiles about people’s weights). For example: A z-score of 1 is 1 standard deviation above the mean. A score of 2 is 2 standard deviations above the mean.
