Big Ideas
  • Graphs can be used as tools to identify and distinguish between different types of relationships in data.
  • Understanding the visual differences between linear and non-linear relationships is fundamental to analyzing bivariate data.
Essential Questions
  • How can you tell if a set of data suggests a linear relationship when looking at a graph?
  • What are some differences between data sets that show a linear relationship and those that do not?
  • Why is it important to be able to distinguish between linear and non-linear relationships in data?
  • How can misinterpreting the type of relationship in data affect your conclusions?
  • What strategies are useful for analyzing data sets on a graph?
