In this lesson, the instructor discusses how to determine if a relationship can be modeled. They go through examples of relationships between levels of responsibility and sanity, number of employees and employee productivity, computer brand and quality-to-cost ratio, dating relationships between male and female students, time and the Dow Jones stock index, and price and sales of a product. The instructor evaluates these relationships based on whether there is a clear input and output, if it's functional, and whether there are numbers associated with it. They also discuss the possibility of data existing and whether one of the four functions can be used to model the relationship. Overall, this lesson provides a comprehensive understanding of how to model relationships.
