Abstract
Numerical methods are often suitable for finding answers to pre-defined questions. While graphical methods are less restrictive. Statistical representations are useful in understanding relationships between variables. They are also useful in identifying distinct points and subsets of data. Such information is very difficult to obtain by numerical methods. In this article, using a real data set, some types of bivariate data representations are introduced.
