Definitions:

Distribution

The way in which something is shared out among a group or spread over an area, or in statistics, how values in a dataset are spread out.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the members of a group differ from the mean value of the group.

Normal Distribution

A probability distribution that is symmetric around the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Standard Deviation

A gauge for the extent of variability or scatter among a group of numbers, highlighting the deviation of these values from their average.
