- 1.1: Visualisation and Transformation of Data
- A brief discussion of techniques for exploration of data with visualization and transformation. Not terribly technical, but does examine techniques often considered to be advanced.
- 1.3: Three Popular Data Displays
- Graphical representations of large data sets provide a quick overview of the nature of the data. A population or a very large data set may be represented by a smooth curve. This curve is a very fine relative frequency histogram in which the exceedingly narrow vertical bars have been omitted. When a curve derived from a relative frequency histogram is used to describe a data set, the proportion of data with values between two numbers a and b is the area under the curve between a and b, as
