Strategies
An ability to read statistical displays as well as a decent knowledge of statistical vocabulary are needed to ensure this exercise is done accurately and efficiently.
 * 1) In a display, the center is in the middle of the display but pulled in a direction of any skew.
 * 2) Data that is nicely patterned and close to each other (in heaps) tend to have smaller spread.

Real-life applications

 * 1) Dot plots, as most of statistics, can be found in everyday media to display information to consumers.
