What is Data Analysis? There are different types of statistical analysis techniques that can be applied to a wide range of data, industries and applications. The strength of tables is that they can accurately present information that cannot be presented with a graph. Whereas statistics and data analysis procedures generally yield their output in numeric or tabular form, graphical techniques allow such results to be displayed in some sort of pictorial form.
