Data can be "distributed" (spread out) in different ways. But in many cases the data tends to be around a central value, with no bias left or right, and it gets close to a "Normal Distribution" like …

Oct 23, 2020 · In a normal distribution, data is symmetrically distributed with no skew. When plotted on a graph, the data follows a bell shape, with most values clustering around a central …
