Graphical Summary Computation (Khattak)
How can intuition about a dataset be developed beyond computation of simple descriptive statistics?
Generating descriptive statistics, such as numerical summaries, helps quantify various aspects of a dataset. However, these techniques alone fail to capture any trends or patterns hidden in the dataset that can be easily identified by humans.
The trends and patterns hidden in a dataset are identified by stimulating visual perception of humans through generating various charts.
Various graphical summaries are generated from the dataset, including bar chart, histogram, scatter plot, cross-tabulation, and box and whisker plot.

A dataset consists of marketing spend data for TV, print and social media channels over the span of several years (1). It needs to be determined whether the dataset contains any interesting patterns that can provide insight as to how the spend data differs across these channels (2). A line chart is created that depicts the marketing spend for each of the channels across all years, based on which it is determined that the print spend has drastically reduced while there has been a steady increase in social media spend (3).
