A set of data is arranged in such a order in which value cluster is placed in the middle of the range and rest taper is placed at their extremes. Height is the example of normal distribution pattern. Normal distribution sometimes is represented in the form graphical pattern .Because of its flared shape , This representation is known as bell curve. Mean , mode & median all three are same in normal distribution.
A normal distribution is also known as Gaussian distribution .
Characteristics of normal distribution –
It is symmetric and bell shaped.
For all values of x( -8 and 8), normal distribution will represent continuous function .
Value of x lies between -8 to 8.
Normal representation covered the area upto 1.0.
Normal distribution is more denser in the center and less denser at the extremes.
