z = (x - mean of x)/ std dev of x I thought this website was pretty good: http://www.jrigol.com/Statistics/TandZStatistics.htm
z=x-mean / sd
A z-chart in statistics is a chart that contains the values that represent the areas under the standard normal curve for the values between 0 and the relative Z-score.
In statistics, letter such as; a,..x..,z, is a variable used to represent an unknown value.
Z-score boundaries are a part of the study of statistics. Z-scores are given by published tables. They refer to the proportion of values that lie between a number, Z and the mean.
z score is defined as z = (x-mean)/sd, where mean is the mean of the sample (or population) and sd is the standard deviation of the sample or the population. x is the raw score. z-score standardizes the data. The standardized data will have a zero mean and unit variance. It has numerous applications in statistics.

In statistics, the z-scale results from a transformation by which a Gaussian (Normal) distribution with any mean and variance is converted to a standard form: the z-score. This is tabulated so that inferences may be drawn from observed data.
Yes. For example, consider a standard normal curve. z = 1 and z = -1 happen to lie at the inflection points of the normal curve.

Yes, although the z-scores associated with p-values of 0.01 and 0.05 have special significance, perhaps mostly for historical reasons, all possible z-scores from negative infinity to positive infinity have meaning in statistical theory and practice.
Another term for z-scores is standard scores. Z-scores indicate how many standard deviations a data point is from the mean of its distribution, allowing for comparison between different datasets. They are commonly used in statistics to standardize scores and facilitate further analysis.
