Cons Of A Histograms

A Normal Distribution
A common pattern is the bell–shaped curve known as the “normal distribution.” In a normal distribution, points are as likely to occur on one side of the average as on the other.
Right Skewed Distribution
The skewed distribution is a symmetrical because a natural limit prevents outcomes on one side
Bimodal Distribution
The Bimodal distribution looks like a camals two humpsThe outcomes of two processes with different distributions are combined in one set of data
