Deviation of mean
WebThe standardized normal distribution is a type of normal distribution, with a mean of 0 and standard deviation of 1. It represents a distribution of standardized scores, called z-scores, as opposed to raw scores (the actual data values).A z-score indicates the number of standard deviation a score falls above or below the mean.Z-scores allow for comparison … WebThat equation will have a fixed mean and standard deviation, and taking more and more samples simply gives you more confidence in your estimate of the mean and standard deviation.
