Random Variable

A variable whose values depend on outcomes of a random phenomenon. It can be discrete or continuous.

Standard Deviation

A metric that quantifies the spread or variation of a dataset in comparison to its average value.

Normal Model

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

Standard Deviation

A criterion for evaluating the extent of scattering or variation present in a dataset.
