Skills
  • contrast (bivariate sets of data that suggest a linear relationship with those that do not from a graphical representation) #dok2
  • identify (types of relationships in bivariate data using graphs) #dok1
  • analyze (patterns in bivariate data to determine linearity or non-linearity) #dok2
Learning Targets
  • I can identify types of relationships between two variables in a scatter plot. #dok1
  • I can distinguish between linear and non-linear relationships in bivariate data using a graph. #dok2
  • I can contrast sets of data that show linear associations with those that do not using graphical representations. #dok2
  • I can analyze patterns in graphs to determine if the relationship between variables is linear or non-linear. #dok2
Big Ideas
  • Patterns in bivariate data reveal important information about the type of relationship between variables.
  • Different types of relationships (linear, non-linear, no relationship) can be observed and interpreted visually through graphical representations.
Essential Questions
  • How can you tell if two variables have a linear or non-linear relationship by looking at a graph?
  • What features of a scatter plot help you distinguish between different types of associations in bivariate data?
  • Why is it important to determine whether a relationship is linear or non-linear?
  • What real-world situations might produce linear versus non-linear data patterns?
  • How does visually interpreting bivariate data help in making predictions or drawing conclusions?
