then the Z-score distribution will be normal, and you will be dealing with a standard normal distribution. You can then make assumptions about the proportion of observations below or above specific Z-values. If however, the original
The table lists the probability of a value falling below a particular z-score on a normal distribution. A z-score of 1.645, for instance, is associated with {eq}P(Z \leq z) = .95 {/eq}, meaning that 95% of the values in the distribution fall below the value with that z-score ...
Body mass index (BMI) and waist circumference (WC) have limitations in stratifying cardio-metabolic risks. Another obesity measure, A Body Shape Index (ABSI), has been introduced but its applicability remains limited. To address this, the z-score of the

Suppose x n(1, 2), what is the z-score of x = 6? Normal Distribution: The normal distribution is used in Central limit theorem as it says that if random variable has finite mean and variance, then the sampling distribution of a statistic (like sample mean with large enough sample s...

Body mass index (BMI) has limited accuracy for predicting cardiovascular diseases (CVD) and is not capable of identifying sarcopenic obesity, the combination of sarcopenia (an age-associated decline in muscle mass and physical function) and obesity. To overcome this, the z-score of the log-trans...
The z-score is positive when the observed value is above the mean. z‑Scores have a mean of zero and a standard deviation of one. It is informative when the empirical distribution is close to a normal distribution. In such cases, z‑scores may be used to compare relative locations of...
