Chapter 2 Graphical methods for presenting data
GRAPHICAL METHODS FOR PRESENTING DATA 15 Example 4: Production line data If there is more than one significant figure in the data, the extra digitsare cut (or truncated), not rounded, to the nearest value; that is to say, 2.97would become 2.9, not 3.0. To illustrate this, consider the following data on lengths of items on a production line ...
