Normal Distributions
A bell-shaped distribution that is symmetric about the mean, indicating that data near the mean are more frequent in occurrence than data far from the mean.
Standard Deviation
A measure of the dispersion or variability within a set of data points, representing how spread out the values are from the mean.
Z-Score
Scores for the standard normal distribution measured in standard deviation units.
Standard Normal Distribution
The standard normal distribution is a special case of the normal distribution with a mean of zero and a standard deviation of one, used in z-tests.
