WebA z-score measures the distance between a data point and the mean using standard deviations. Z-scores can be positive or negative. The sign tells you whether the observation is above or below the mean. For example, a z-score of +2 indicates that the data point falls two standard deviations above the mean, while a -2 signifies it is two standard ...

The standard normal distribution is a probability distribution, so the area under the curve between two points tells you the probability of variables taking on a range of values. The total area under the curve is 1 or 100%. Every z score has an associated p value that tells you the probability of all values below or above that … Ver mais All normal distributions, like the standard normal distribution, are unimodaland symmetrically distributed with a bell-shaped curve. However, a normal distribution can take on any value as its mean and standard … Ver mais When you standardize a normal distribution, the mean becomes 0 and the standard deviation becomes 1.
