Normal distribution is a bell shaped and symmetrical with location parameter \(\mu\) and variation . 0000000016 00000 n We've encountered a problem, please try again. When plotted on a graph, the data follows a bell shape, with most values clustering around a central region and tapering off as they go further away from the center. Characterization aspects sometimes show up in unexpected places, cf. It is a symmetrical arrangement of a data set in which most values cluster in the mean and the rest taper off symmetrically towards either extreme.

Many areas of EE rather are. It is made relevant by the Central Limit Theorem, which states that the averages obtained from independent, identically distributed random variables tend to form normal distributions, regardless of the type of distributions they are sampled from. Most values are located near the mean; also, only a few appear at the left and right tails.
