WebA z-score represents the number of standard deviations away from the mean any given data point is in a normal distribution. You take the SAT and score 1100. The mean score for the SAT is 1026 and the standard deviation is 209. How well did you score on the test compared to the average test taker? WebCharacteristics of Z-scores. The scores can be positive or negative. For data that is symmetric (i.e. bell-shaped) or nearly symmetric, a common application of Z-scores for …

WebThe Fenton z-score was the most predictive factor considering the fetal growth assessment showing high sensitivity. Antenatal factors play a role in NEC pathogenesis. This study aimed to investigate the predictive value of fetal ductus venosus doppler (DV) for NEC in fetal growth restriction fetuses (FGRF) and to assess the predictive accuracy ... Weba. the score's distance from the mean; whether the score is greater or less than the mean A deviation score is more informative than a raw score because it a. describes the shape of the distribution b. has a greater numeric value c. is a transformation of the raw score d. gives the score's location relative to the mean build master top
