Z Score = (measurement – mean)/ standard deviation A negative z score indicates measurement is smaller than the mean while a positive z score says that the measurement is larger than the mean. Example: A teacher gives a test and the class average is 74 with a standard deviation of 6.

Individuals with Loeys-Dietz syndrome often have skeletal problems including premature fusion of the skull bones (craniosynostosis ), an abnormal side-to-side curvature of the spine (scoliosis ), either a sunken chest (pectus excavatum) or a protruding chest (pectus carinatum ), an inward- and upward-turning foot (
A standard normal distribution (SND). A z-score, also known as a standard score, indicates the number of standard deviations a raw score lays above or below the mean. When the mean of the z-score is calculated it is always 0, and the standard deviation (variance) is always in increments of 1.May 30, 2019
Body mass index z-scores, also called BMI standard deviation (s.d.) scores, are measures of relative weight adjusted for child age and sex. In clinical practice, BMI-for-age growth charts can be used to determine a child's BMI-for-age percentile and to track relative weight status through childhood and adolescence.Mar 29, 2006
