Describe a real-world problem scenario of variation among influencing variables of your example. You can find examples of scenarios in Section 2.5, but you want to use one of your own examples. Include details of the scenario that clearly identify the variables (both input variable and output variable) and how they influence each other in ways that can be explained as variation. Sketch a graph of your example scenario (which will be more of a theoretical graph than a graph of actual values). Discuss any circumstances that might affect the variation in your example scenario.
