Reply With QuoteThe normal distributions are very important class of statistical distributions. All
normal distributions are symmetric and have bell=shaped density curves with a
single peak. Both the normal and Symmetrical distributions are U-Shaped and
equal from both sides.
The normal distribution is considered the most prominent probability distribution
in statistics. There are several seasons of this, First, the normal distribution is
very tractable analytical, that is, a large number of results involving. This
distribution can be derived in explicit from. second, the normal distribution arises
as the outcome of the central limit theorem, which states that under mild
conditions the sum of a large number of random variables is distributed
approximately normally. Finally the “bell” shape of the normal Distribution makes
it a convenient choice for modeling a large variety of random variables
encountered in practice.
Definition of Symmetrical Distribution’
A situation in which the values of variables occur at regular frequencies, and the
man median and made occur at the same point. Unlike asymmetrical distribution,
symmetrical distribution does not skew. A symmetrical distribution is commonly
shaped like a bell curve when depicted on a graph. If a line is drawn down the
middle of the graph, the two sides will mirror each other.
Hint: Also called a “symmetric distribution or “Normal Distribution”
